ii. Brief description of the nature of the project
Khairagura Opencast Project is an existing Opencast Coal Mine belongs to the
Singareni Collieries Company Limited. The Khairagura block forms a virgin coal–
bearing block with an aerial extent of 8.80 Km. long in the Northwestern extremity of
Tandur leasehold in Asifabad Mandal of Adilabad district. It forms a part of the 45
Km. long Bellampalli-Goleti coal belt. In this block 66 bore holes with a total of 13265
m. were drilled up to a maximum depth of 300 m. Total estimated reserves in this
block are 106.31 Mt.
Feasibility report of Khairagura opencast project was initially prepared in 1988 upto a
depth of 107 m. with Dragline, Shovel & Dumper combination based on technical
feasibility study made by CMPDIL, Ranchi with coal and OB removal by
departmental HEMM. The seams proposed for working are II seam and top and
bottom sections of middle seam in the descending order. The project was envisaged
to produce 15.23 Mt of coal by removing 77.69 M.Cum. of overburden with an
average stripping ratio of 5.10 cu m/t and rated capacity of 0.72 Mt per annum. The
life of the project was estimated as 25 years and with average grade of the coal as
‘E’. After approval of the project by the Board on 05.02.1989, it was submitted to the
Govt. of India for sanction on 16.03.1989 and the same was not approved due to
non-availability of land for compensatory afforestation.
Singareni Collieries Company Limited
3 Prefeasibility Report of Khairagura OCP
Subsequently, the Feasibility Report was revised considering OB removal by hiring
of HEMM and Coal by departmentally in January 2001 and submitted to Technical
Committee of SCCL Board.
The brief particulars of changes made in the original FR are as under.
a) Though shovel-dumper & dragline combination was proposed earlier in
the project, shovel-dumper combination with hiring of HEMM for OB
removal is proposed as it was cheaper.
b) Extraction of Bottom seam with 3.13 Mt of ‘C’ grade coal is added along
with No.II seam, Top and Bottom sections of Middle Seam which were
envisaged in the original FR, keeping in view the latest economics.
c) Total land requirement is brought down from 500 Ha as per original FR to
298 Ha. (Including 140.30 Ha. of forest land). The requirement of forest
land has been reduced from 336.50 Ha. to 140.30 Ha. by shifting the
external dump to non forest land.
The proposal was approved by SCCL Board in its meeting held on 20.09.2001 with a
capital investment of Rs 47.46 Crores and rated capacity of 0.72 Mtpa.
The important project parameters of the Feasibility Report are as follows.

Forest clearance for diversion of 140.38 Ha of Forest land required for Khairagura
OCP has been obtained Vide Ref. F.No.8-102/200D-FC dated 10.09.2003.
Forest clearance for diversion of 29.85Ha of forest land towards approach road and
power transmission line etc. obtained for Khairagura underground project Vide Ref.
F.No.8-28/94-FC. Dated.28.09.2000. Since the underground project is deferred and
this approach road is also required for Khairagura OCP, the above land requirement
is shown in the RFR Khairagura OCP.
Revised Feasibility Report of Khairagura Opencast Mine
Keeping in view, the experience of working opencast mines at greater depths and
high stripping ratios, it is felt feasible to extend the present project upto a maximum
depth of 222m as against 120m in the existing project. With this the total extractable
reserves will increase to 66.87 Mt and corresponding OB to be removed will be
584.77 M.Cu.m.
This additional area cannot be proposed as a separate UG project as the area is
falling within the high flood level of Vattivagu irrigation project. The optimization of
Singareni Collieries Company Limited
4 Prefeasibility Report of Khairagura OCP
project is technically feasible by combining with the existing Khairagura OC project.
This will also minimize the construction period. Hence, it is proposed to formulate the
Revised Feasibility Report with a total rated capacity of 2.50 Mtpa upto a maximum
depth of 222m.
Total extractable reserves of the present proposal are 66.87 Mt. with total OB
volume of 584.77 M.Cu.m. The average stripping ratio of the revised proposal is
estimated at 8.74.
Revised Feasibility Report of Khairagura Open Cast Project was approved by the
Board Vide letter No CRP/CS/054/899 Dt. 13-09-2006 with an estimated capital cost
of Rs.92.46 Crores, for a targeted annual output of 2.50 Mt. and with the project life
of 27 years. It is proposed to excavate OB by out sourcing and coal by departmental
HEMM. The Environmental Clearance for this project was issued vide Lr.No.J-
110156892007-1A.II (M) Dt.22-10-2007.
Present proposal
Keeping in view of the increase in demand in the SCCL command area and limited
scope for enhancing production in the short run, it is proposed to enhance the
capacities of presently operating opencast mines to their optimum levels with short
gestation.
Khairagura OCP is one of such projects wherein the potential production capacity
can be enhanced from 2.5 MTPA to 3.12 MTPA with minimum additional facilities
and with short gestation.
iii. Need for the project and its importance to the country and or region
The Singareni Collieries Company Limited is a state owned Public Sector Company
operating 35 Nos. of Underground mines and 15 No. of Opencast mines. It has been
exploiting coal for more than 120 years. Out of 470 Km long Pranhita Godavari
valley Coal field, the 350 Km sector is lying mostly in the South Indian State of
Andhra Pradesh. Over the years, the Company had expanded its exploitation
activities in Adilabad, Karimnagar, Warangal and Khammam districts of Andhra
Pradesh.
SCCL is taking the following steps for increasing the coal production.
1) Reconstruction of existing mines for optimum production by intermediate and
high technology.
2) Improving the productivity in the existing mines by improving the utilization of
the equipment.
3) Opening of new mines in the adjoining/superjacent areas/seams for higher
production.
4) Adopting opencast method of mining wherever possible for high rate of
production.
5) Conversion of shallow underground workings to opencast method for
extraction of balance coal reserves.
6) Extension of the existing opencast workings to further dip side upto optimum
level.
7) Enhancing the production of existing opencast projects where ever possible
Singareni Collieries Company Limited
5 Prefeasibility Report of Khairagura OCP
In this context, viability of enhancement of production of existing Khairagura
Opencast Project is examined and found amenable for enhancement by enhancing
the capacity of HEMM.
iv. Demand-Supply gap
The total availability of coal from the existing projects, projects under implementation
and approved projects is inadequate to meet the total demand and a substantial gap
remains unfulfilled. The following statement reveals the gap and justifies planning of
additional new projects and reconstructing the existing Projects. The terminating
year production projections of XI Plan can only be met by starting new mines and by
reorganizing & reconstructing some of the existing mines to step up production with
advanced technology.
The main consumers of coal are power sector companies like NTPC, APGENCO,
KPCL, MSEB, cement and other industries like Heavy water plant, Brick etc.

The present proposal of, expansion of existing Khairagura Opencast Project, is
planned to increase production capacity from 2.5 MTPA to 3.12 MTPA without
increase in ML area.
v. Imports vs. Indigenous production
Certain quantity of coal is being imported to mitigate demand-supply gap in the
country. In order to reduce the imports and to increase the production capacities, it is
proposed to increase the capacity of the existing Khairagura Open Cast Project.
vi. Export possibility
There is no possibility of export of coal from this mine as there is sufficient demand
for industries located in the region and also elsewhere in AP and India
vii. Domestic / export markets
The coal produced is fed to the major domestic customers namely Power sector,
Cement industries, fertilizers, brick industries etc
viii. Employment generation(Direct and Indirect) due to the project:
This is an existing project, which is considered for further production enhancement.
Due to opening of this project direct employment was generated in the company for
working various operations in the mine. The total manpower deployed by the
company in this mine is 366.
Apart from the direct employment, Indirect employment may also be generated to lot
many in the form of Coal transportation, picking of Shale / Stone from the conveyor

6. PROPOSED INFRASTRUCTURE
i. Industrial area (Processing area)
The existing office buildings, workshops and CHP will be catering the needs for
proposed expansion project.
ii. Residential area (Non processing area)
No additional township is required for the envisaged proposal. The existing township
is sufficient to cater the needs of persons employed in the mine.
iii. Green belt
Proposed plantation details
• OB Dump(External) plantation : 392.62 Ha
• OB Dump(Internal ) Plantation : 286.41 Ha
Singareni Collieries Company Limited
19 Prefeasibility Report of Khairagura OCP
• Other areas : 140.20 Ha
• Total Area of Plantation : 819.23 Ha
Till now plantation was done in an area of 232.41 Ha over the external OB dumps
and mine premises. And it is proposed to carry out plantation as a part of Green belt
development at areas along the roads, vacant lands along ML boundary and also in
the township outside the lease area.
iv. Social Infrastructure
Social Infrastructure available in the area will cater the needs of the employees
working in the mine. No additional social infrastructure is proposed in the project
v. Connectivity(Traffic and transportation road/ Rail/Metro/ Water ways etc)
Presently, the coal dispatches of Khairagura OCP are being handled by RKP CHP,
which is situated at about 63KM. Part of the coal is being dispatched by off-loading
through Wharf loading system to the customers from nearby Rebbana Railway
Station.
A Coal Handling Plant of 4.0 M.T. of annual capacity is envisaged in this area and is
under construction at Rebbana Rly Station. This CHP is proposed to be served by a
6 Kms. long railway siding drawn cut from Asifabad Road Railway Station of south
Central Railway.
vi. Drinking water management (Source and Supply of water)
Seepage water is collected in the sumps created in the dip most area of the quarry.
The water is pumped to the surface and treated by RO system before it is used for
drinking. And the remaining water is being used for other industrial purpose.
vii. Sewerage system
The sewerage water is being treated in 1.5 MLD capacity STP in Goleti Township for
newly constructed quarters. The sewage water coming out from existing old quarters
and office premises is being treated in septic tank followed by soak pit.
viii. Industrial waste management
The major effluent source is mine water pumped out from the mine, which is being
let out into natural streams after removal of suspended solids. The other source of
concern would be the domestic and service building effluents. The domestic effluent
is being treated in septic tank followed by soak pits.
In the coal extraction process, coal containing impurities such as shale or sometimes
sandstone is being transported to the coal handling plant. There, the shale and sand
stone is being picked out manually. This solid waste is in the form of lumps.
The solid waste from the townships is being collected from the collection bins and
tricycles provided by SCCL. The domestic solid waste collected is being transported
to the disposal sites of SCCL. The solid waste disposal sites are identified in the low-
lying areas, over burden dumps and subsidence areas of SCCL. Hence, no
appreciable impact is anticipated due to disposal of solid wastes.
Singareni Collieries Company Limited
20 Prefeasibility Report of Khairagura OCP
There is no problem for collection, handling and transport of solid wastes and there
will not be any subsequent pollution of air, water and soil due to disposal or reuse of
solid wastes.
ix. Solid waste management
The following design criteria have been considered for waste dumps
i) Separate spoil dumps for Topsoil and other OB.
ii) Maximum height of Top soil dump will be 10 meters.
iii) Main OB to be dumped in 30 m high decks.
iv) 30 m berm width for allowing safe transport in external dumps.
v) Dump slope for each deck to be at 37 ½ 0
and overall slope 26.50
vi) Track Dozers will be deployed for shaping the dumps.
vii) The maximum dump height proposed for External dump yard-1&2 will be 90m
and for External dump yard-3 it will be 120m above the ground level.
viii) The Final height of the internal dump yard will be 90m above the ground level.

Total 573.91 10.86 584.77
x. Power requirement & supply/source
The source of power for the project is from 132 kV sub-station, Mandamarri. This
sub-station is having sufficient spare capacity to meet the power requirement of
expansion project also. One overhead transmission line of 33 KV supplies power
from this substation to Goleti which is 12 km away from the Khairagura project, from
there the power required for the project is drawn.
The power requirement for this project is about 1.748 MVA (as OB removal is by
hiring HEMM, which are mainly with diesel operated equipment).
7. REHABILITATION AND RESETTLEMENT (R&R) PLAN:
This is already operating project and no new land is required for this project.
Production enhancement is proposed by optimizing the existing HEMM. Hence no
R & R is involved.
8. PROJECT SCHEDULE:
i. Likely date of start of construction and likely date of completion(Time
schedule for the project to be given)
Singareni Collieries Company Limited
21 Prefeasibility Report of Khairagura OCP
The project is already operating opencast mine and proposed to enhance its rated
capacity from 2.5 MTPA to 3.12 MTPA. The project under the present proposal is a
working mine, hence it is expected to achieve the rated capacity in the 1st
year itself
(i.e. 2013-14) and to be closed in the year 2029-30 (17 years life).
9. ANALYSIS OF PROPOSAL (FINAL RECOMMENDATION):
Financial and social benefits with special emphasis on the benefit to the local
people including tribal population, if any, in the area.
IMPROVEMENT IN PHYSICAL INFRASTRUCTURE
This project is located in the Adilabad district of Andhra Pradesh. The project is also
located in an area where communications and other facilities are not up to the mark.
The following physical infrastructure facilities will further improve due to proposed
project.
• Road Transport facilities
• Communications
• Housing facilities
• Water supply and sanitation
• Power
• Medical, Educational and social benefits will be made available to the nearby
civilian population in addition to the workmen employed in the project.
IMPROVEMENT IN SOCIAL INFRASTRUCTURE
Coal mining and agriculture is the basic sector of employment for the local people in
this area. This project is lead to indirect employment opportunity. Employment is
expected during civil construction period, in trade, garbage lifting, sanitation and
other ancillary services, Employment in these sectors is primarily temporary or
contractual and involvement of unskilled labor is more. A major part of this labor
force is mainly from local villagers who are expected to engage themselves both in
agriculture and project activities. This will enhance their income and lead to overall
economic growth of the area.
The following changes in socio-economic status are expected to take place with this
project.
i) The project is having a strong positive employment and income effect, both direct
as well as indirect. Migrant - non-migrant ratio will shift towards migrant side
because a number of people will migrate towards the central region of study
circle in the years to come. This will happen because of better indirect
employment opportunities due to this project.
ii) The project is going to have positive impact on consumption behavior by way of
raising average consumption and income through multiplier effect.

Brief description of the nature of the project Khairagura Opencast Project is an existing Opencast Coal Mine belongs to the Singareni Collieries Company Limited. The Khairagura block forms a virgin coal– bearing block with an aerial extent of 8.80 Km. long in the Northwestern extremity of Tandur leasehold in Asifabad Mandal of Adilabad district. It forms a part of the 45 Km. long Bellampalli-Goleti coal belt. In this block 66 bore holes with a total of 13265 m. were drilled up to a maximum depth of 300 m. Total estimated reserves in this block are 106.31 Mt. Feasibility report of Khairagura opencast project was initially prepared in 1988 upto a depth of 107 m. with Dragline, Shovel & Dumper combination based on technical feasibility study made by CMPDIL, Ranchi with coal and OB removal by departmental HEMM. The seams proposed for working are II seam and top and bottom sections of middle seam in the descending order. The project was envisaged to produce 15.23 Mt of coal by removing 77.69 M.Cum. of overburden with an average stripping ratio of 5.10 cu m/t and rated capacity of 0.72 Mt per annum. The life of the project was estimated as 25 years and with average grade of the coal as ‘E’. After approval of the project by the Board on 05.02.1989, it was submitted to the Govt. of India for sanction on 16.03.1989 and the same was not approved due to non-availability of land for compensatory afforestation.
  • 19. Singareni Collieries Company Limited 3 Prefeasibility Report of Khairagura OCP Subsequently, the Feasibility Report was revised considering OB removal by hiring of HEMM and Coal by departmentally in January 2001 and submitted to Technical Committee of SCCL Board. The brief particulars of changes made in the original FR are as under. a) Though shovel-dumper & dragline combination was proposed earlier in the project, shovel-dumper combination with hiring of HEMM for OB removal is proposed as it was cheaper. b) Extraction of Bottom seam with 3.13 Mt of ‘C’ grade coal is added along with No.II seam, Top and Bottom sections of Middle Seam which were envisaged in the original FR, keeping in view the latest economics. c) Total land requirement is brought down from 500 Ha as per original FR to 298 Ha. (Including 140.30 Ha. of forest land). The requirement of forest land has been reduced from 336.50 Ha. to 140.30 Ha. by shifting the external dump to non forest land. The proposal was approved by SCCL Board in its meeting held on 20.09.2001 with a capital investment of Rs 47.46 Crores and rated capacity of 0.72 Mtpa. The important project parameters of the Feasibility Report are as follows. S.No. Parameter details 1 Total mineable coal (Mt) 16.713 2 Total Over Burden (M cu m) 90.32 3 Average Stripping Ratio 1:5.4 4 Rated Capacity (Mtpa) 0.72 5 Life of the project (Years) 24 6 Grade of the Coal ‘C/E’ 7 Capital (Rs.crores) 47.46 Environmental Clearance for this project was issued by MOEF, GOI vide Lr. No. J-11015/36/2003-1A-.II (M) dated.16-09-2004. Forest clearance for diversion of 140.38 Ha of Forest land required for Khairagura OCP has been obtained Vide Ref. F.No.8-102/200D-FC dated 10.09.2003. Forest clearance for diversion of 29.85Ha of forest land towards approach road and power transmission line etc. obtained for Khairagura underground project Vide Ref. F.No.8-28/94-FC. Dated.28.09.2000. Since the underground project is deferred and this approach road is also required for Khairagura OCP, the above land requirement is shown in the RFR Khairagura OCP. Revised Feasibility Report of Khairagura Opencast Mine Keeping in view, the experience of working opencast mines at greater depths and high stripping ratios, it is felt feasible to extend the present project upto a maximum depth of 222m as against 120m in the existing project. With this the total extractable reserves will increase to 66.87 Mt and corresponding OB to be removed will be 584.77 M.Cu.m. This additional area cannot be proposed as a separate UG project as the area is falling within the high flood level of Vattivagu irrigation project. The optimization of Singareni Collieries Company Limited 4 Prefeasibility Report of Khairagura OCP project is technically feasible by combining with the existing Khairagura OC project. This will also minimize the construction period. Hence, it is proposed to formulate the Revised Feasibility Report with a total rated capacity of 2.50 Mtpa upto a maximum depth of 222m. Total extractable reserves of the present proposal are 66.87 Mt. with total OB volume of 584.77 M.Cu.m. The average stripping ratio of the revised proposal is estimated at 8.74. Revised Feasibility Report of Khairagura Open Cast Project was approved by the Board Vide letter No CRP/CS/054/899 Dt. 13-09-2006 with an estimated capital cost of Rs.92.46 Crores, for a targeted annual output of 2.50 Mt. and with the project life of 27 years. It is proposed to excavate OB by out sourcing and coal by departmental HEMM. The Environmental Clearance for this project was issued vide Lr.No.J- 110156892007-1A.II (M) Dt.22-10-2007. Present proposal Keeping in view of the increase in demand in the SCCL command area and limited scope for enhancing production in the short run, it is proposed to enhance the capacities of presently operating opencast mines to their optimum levels with short gestation. Khairagura OCP is one of such projects wherein the potential production capacity can be enhanced from 2.5 MTPA to 3.12 MTPA with minimum additional facilities and with short gestation. iii. Need for the project and its importance to the country and or region The Singareni Collieries Company Limited is a state owned Public Sector Company operating 35 Nos. of Underground mines and 15 No. of Opencast mines. It has been exploiting coal for more than 120 years. Out of 470 Km long Pranhita Godavari valley Coal field, the 350 Km sector is lying mostly in the South Indian State of Andhra Pradesh. Over the years, the Company had expanded its exploitation activities in Adilabad, Karimnagar, Warangal and Khammam districts of Andhra Pradesh. SCCL is taking the following steps for increasing the coal production. 1) Reconstruction of existing mines for optimum production by intermediate and high technology. 2) Improving the productivity in the existing mines by improving the utilization of the equipment. 3) Opening of new mines in the adjoining/superjacent areas/seams for higher production. 4) Adopting opencast method of mining wherever possible for high rate of production. 5) Conversion of shallow underground workings to opencast method for extraction of balance coal reserves. 6) Extension of the existing opencast workings to further dip side upto optimum level. 7) Enhancing the production of existing opencast projects where ever possible
  • 20. Singareni Collieries Company Limited 5 Prefeasibility Report of Khairagura OCP In this context, viability of enhancement of production of existing Khairagura Opencast Project is examined and found amenable for enhancement by enhancing the capacity of HEMM. iv. Demand-Supply gap The total availability of coal from the existing projects, projects under implementation and approved projects is inadequate to meet the total demand and a substantial gap remains unfulfilled. The following statement reveals the gap and justifies planning of additional new projects and reconstructing the existing Projects. The terminating year production projections of XI Plan can only be met by starting new mines and by reorganizing & reconstructing some of the existing mines to step up production with advanced technology. The main consumers of coal are power sector companies like NTPC, APGENCO, KPCL, MSEB, cement and other industries like Heavy water plant, Brick etc. Figures in Million Tonnes XI Plan XII Plan Sl.No Particulars 2011-12 2012-13 2013-14 2014-15 2015-16 2016-17 1 Demand 55.75 57.60 59.40 63.70 71.30 73.50 2 Production 52.20 53.10 54.30 55.10 56.10 57.10 3 Gap -3.55 -4.50 -5.10 -8.60 -15.20 -16.40 The present proposal of, expansion of existing Khairagura Opencast Project, is planned to increase production capacity from 2.5 MTPA to 3.12 MTPA without increase in ML area. v. Imports vs. Indigenous production Certain quantity of coal is being imported to mitigate demand-supply gap in the country. In order to reduce the imports and to increase the production capacities, it is proposed to increase the capacity of the existing Khairagura Open Cast Project. vi. Export possibility There is no possibility of export of coal from this mine as there is sufficient demand for industries located in the region and also elsewhere in AP and India vii. Domestic / export markets The coal produced is fed to the major domestic customers namely Power sector, Cement industries, fertilizers, brick industries etc viii. Employment generation(Direct and Indirect) due to the project: This is an existing project, which is considered for further production enhancement. Due to opening of this project direct employment was generated in the company for working various operations in the mine. The total manpower deployed by the company in this mine is 366. Apart from the direct employment, Indirect employment may also be generated to lot many in the form of Coal transportation, picking of Shale / Stone from the conveyor Singareni Collieries Company Limited 6 Prefeasibility Report of Khairagura OCP belts, supply of raw material like fly ash bricks, general conveyance of persons to the mine from their location by means of hired vehicles, housekeeping, out sourced OB removal etc. 3.

Assessment of infrastructure demand (Physical & Social) The proposed project is planned to develop in the existing coal belt of the company and well established infrastructure such as road, rail, railway siding, CHP, Township, communication, power supply arrangements, etc. are available. v. Amenities/Facilities The facilities are provided to the persons connected to mining operation whether direct or indirect are: Residential quarters, Rest shelters for taking rest, Canteen facilities at subsidized rates, Washing/bathing facilities, provision of motor cycle/Cycle sheds, provision of drinking water points, sanitation facilities ,first aid and medical facilities etc. 6. PROPOSED INFRASTRUCTURE i. Industrial area (Processing area) The existing office buildings, workshops and CHP will be catering the needs for proposed expansion project. ii. Residential area (Non processing area) No additional township is required for the envisaged proposal. The existing township is sufficient to cater the needs of persons employed in the mine. iii. Green belt Proposed plantation details • OB Dump(External) plantation : 392.62 Ha • OB Dump(Internal ) Plantation : 286.41 Ha
  • 27. Singareni Collieries Company Limited 19 Prefeasibility Report of Khairagura OCP • Other areas : 140.20 Ha • Total Area of Plantation : 819.23 Ha Till now plantation was done in an area of 232.41 Ha over the external OB dumps and mine premises. And it is proposed to carry out plantation as a part of Green belt development at areas along the roads, vacant lands along ML boundary and also in the township outside the lease area. iv. Social Infrastructure Social Infrastructure available in the area will cater the needs of the employees working in the mine. No additional social infrastructure is proposed in the project v. Connectivity(Traffic and transportation road/ Rail/Metro/ Water ways etc) Presently, the coal dispatches of Khairagura OCP are being handled by RKP CHP, which is situated at about 63KM. Part of the coal is being dispatched by off-loading through Wharf loading system to the customers from nearby Rebbana Railway Station. A Coal Handling Plant of 4.0 M.T. of annual capacity is envisaged in this area and is under construction at Rebbana Rly Station. This CHP is proposed to be served by a 6 Kms. long railway siding drawn cut from Asifabad Road Railway Station of south Central Railway. vi. Drinking water management (Source and Supply of water) Seepage water is collected in the sumps created in the dip most area of the quarry. The water is pumped to the surface and treated by RO system before it is used for drinking. And the remaining water is being used for other industrial purpose. vii. Sewerage system The sewerage water is being treated in 1.5 MLD capacity STP in Goleti Township for newly constructed quarters. The sewage water coming out from existing old quarters and office premises is being treated in septic tank followed by soak pit. viii. Industrial waste management The major effluent source is mine water pumped out from the mine, which is being let out into natural streams after removal of suspended solids. The other source of concern would be the domestic and service building effluents. The domestic effluent is being treated in septic tank followed by soak pits. In the coal extraction process, coal containing impurities such as shale or sometimes sandstone is being transported to the coal handling plant. There, the shale and sand stone is being picked out manually. This solid waste is in the form of lumps. The solid waste from the townships is being collected from the collection bins and tricycles provided by SCCL. The domestic solid waste collected is being transported to the disposal sites of SCCL. The solid waste disposal sites are identified in the low- lying areas, over burden dumps and subsidence areas of SCCL. Hence, no appreciable impact is anticipated due to disposal of solid wastes. Singareni Collieries Company Limited 20 Prefeasibility Report of Khairagura OCP There is no problem for collection, handling and transport of solid wastes and there will not be any subsequent pollution of air, water and soil due to disposal or reuse of solid wastes. ix. Solid waste management The following design criteria have been considered for waste dumps i) Separate spoil dumps for Topsoil and other OB. ii) Maximum height of Top soil dump will be 10 meters. iii) Main OB to be dumped in 30 m high decks. iv) 30 m berm width for allowing safe transport in external dumps. v) Dump slope for each deck to be at 37 ½ 0 and overall slope 26.50 vi) Track Dozers will be deployed for shaping the dumps. vii) The maximum dump height proposed for External dump yard-1&2 will be 90m and for External dump yard-3 it will be 120m above the ground level. viii) The Final height of the internal dump yard will be 90m above the ground level.

Power requirement & supply/source The source of power for the project is from 132 kV sub-station, Mandamarri. This sub-station is having sufficient spare capacity to meet the power requirement of expansion project also. One overhead transmission line of 33 KV supplies power from this substation to Goleti which is 12 km away from the Khairagura project, from there the power required for the project is drawn. The power requirement for this project is about 1.748 MVA (as OB removal is by hiring HEMM, which are mainly with diesel operated equipment). 7. REHABILITATION AND RESETTLEMENT (R&R) PLAN: This is already operating project and no new land is required for this project. Production enhancement is proposed by optimizing the existing HEMM. Hence no R & R is involved. 8. PROJECT SCHEDULE: i. Likely date of start of construction and likely date of completion(Time schedule for the project to be given)
  • 28. Singareni Collieries Company Limited 21 Prefeasibility Report of Khairagura OCP The project is already operating opencast mine and proposed to enhance its rated capacity from 2.5 MTPA to 3.12 MTPA. The project under the present proposal is a working mine, hence it is expected to achieve the rated capacity in the 1st year itself (i.e. 2013-14) and to be closed in the year 2029-30 (17 years life). 9.
