Coal tech-r&d in india

  1. 1. COAL CONSERVATION, UTILISATION AND RESEARCH & DEVELOPMENT IN INDIACOAL CONSERVATION1 Conservation of coal enjoins maximum recovery of in-situ reserves ofcoal. Coal deposits in India occur mostly in thick seams and at shallowdepths. These aspects are taken into account during mine planning andoperation in ensuring maximum recovery.2 Mechanised opencast mining in India is one of the very importanttechnology of coal production of thick seam from shallow depth.. Thepercentage recovery by this method is up to 80% to 90% of the in-situcoal reserves. The coal production from opencast method in Indianmining is more than 75% of total production. This trend is likely tocontinue in near future. The thick seam deposits earlier developed inBord and Pillar method or other methods of underground mining whichhad been standing on pillars for long in absence of a suitable technologyof extraction have now become extractable by opencast mining withHEMM equipment of suitable type. This method has been tried withsuccess in some of the mines of WCL, BCCL, CCL and ECL mineswhere underground mining was carried out in the past under therelatively shallow cover.3 In case of SCCL, the scope for planning for opencast mines is limited,longwall methods are being applied in the case of underground mines toachieve higher underground production with higher percentage ofrecovery.The longwall method of mining is also being implemented in SECL,ECL and BCCL in Coal India.. The overall recovery in longwalltechnology is comparatively more than the recovery in B&P mining .Mines having difficult geo-mining conditions like steep and irregularcoal seam deposits, gassy seams, contiguous and multi-section seams, 1
  2. 2. necessitate the introduction of some specific technology for exploitationof such deposits.For extraction of multi-section seams of thickness more than 4.8 mtrs.methods such as Blasting gallery, Sub-level Caving, and Cable boltinghave been adopted in some of the mines. In Margherita area of NECspecial methods of mining such as, Bhaska method, Tipong method,Shield method, and Flexible roofing have been tried . Presently Tipongmethod and Scraper assisted chamber method are in use.SAND STOWING4 Sand stowing in underground mines is yet another effective means ofcoal conservation, which is widely in use for extraction of coal pillarsfrom underground coal seams and coal seams lying underneath built uparea, such as surface structures, railway lines, roads, rivers, nallahs,Jores, etc. Sand stowing is also used for protection against fire in coalseams.Under Research & Development activities for increased extraction ofcoal, the following projects have been taken up :(i) Optimal extraction of coal in locked up pillars underneath aquifersand fragile ecology - CMRI/SECL(ii) Development of an efficient method of extraction of developedpillars for seam thickness up to 3.5m - SECL(iii) Optimal extraction of coal locked in pillars of multiple and thickseams - NIRM/SCCL(iv) Optimisation of pillar parameters for development and finalextraction of highly inclined seams at SCCL mines - SCCL/ NIRM. 2
  3. 3. (v) Depillaring with cable bolting using LHD at MadhusudanpurColliery - ECLCONTROL OF MINE FIRES & SUBSIDENCEJHARIA COALFIELDIn the Jharia coalfield, at the time of nationalisation of coking coalminesin 1972, there were reportedly, 70 active fires over an area of 17 sq.kms.A number of schemes for control of fires envisaging an outlay of Rs.114.57 crores, are under various stages of implementation. So far thefollowing results have been obtained.1. No. of fires completely Ten. The remaining liquidated 60 fires are by and large under control.2. Fires affect reduction 40%. of surface. Presently 9 sq. km is affected by fire (as per study carried out by international consultants) out of 17.32 sq. km, as per 1986 estimate3. Blanketing done Over 22 million m3 3
  4. 4. 4. Nitrogen flushing done Over 3.0 million m35. Sand stowing done Over 50 million m36 Fire belts reclaimed Joga, Kustore, Ena, and converted into Pootkee, sendra Green Belts. Bansjora Lodna etc.Under IDA credit to the Govt. of India, BCCL received a loan of US $12.00 million for developing a long-term plan for carrying outinvestigation and preparation of recommendation of measures forextinguishing controlling fires and preparation of Environmentalmanagement Plan (EMP) for Jharia Coalfield. M/s GAI-METCHEM, ajoint venture of USA/ Canada was appointed for preparing the ‘FIREFIGHTING PROGRAMME’ and M/S NORWEST MINE SERVICESof Canada for preparation of the EMP; The major observations/findingsare given below.A. FIRE FIGHTING PROGRAMME1. Overall fire shave reduced in area from about 17 sq. km (186) to 9.0sq.km. (196)2. Dhanbad-Patherdih Railway Line (28.km) is endangered by fires andrequires grout stabilisation relocation preferred.3. Adra-Gomoh Railway Line requires protection by isolation trench andwater curtain.4. Ekra, Kari and Catkari jores are endangered by fires and requireimmediate grout stabilisation. 4
  5. 5. 5. Jharia and Kirkend towns and other built up areas are endangered dueto fires and require immediate isolation from fires. Shifting of townshipshave been recommended as a better option.6. Some fires may be excavated as part of profitable opencast miningprojects such as Block-III, Kusunda Block-IV and Tisra.B. PREPARATION OF EMP FOR JHARIA COALFIELD.1. 22,300 families are required to be shifted.2. Predominant air pollution is from road generated dust and vehicleexhaust.3. Contribution of dust by traffic is about 37% of total pollution load inJCF.4. The coalfield contributes about 15% of the total pollution load in theDamodar River.5. Construction Of small reservoirs to the North of the coalfields acrossthe streams is recommended.6. Continue the existing plantation programme and encourage socialforestry.SUBSIDENCE PROBLEM IN RANIGUNJIn the past, prior to nationalisation of coalmines, unscientific mining wascarried out under shallow cover, which has resulted in some areas inRanijunj Coalfield being threatened with subsidence. Illegal mining isaggravating this problem.An apex monitoring committee (AMC) had been constituted with ShriH.B. Ghosh, Ex-DGMS & Retired CMD, CMPDIL as Chairman andrepresentatives of Govt. of West Bengal, DGMS, CMPDIL, ECL, CMRIlocal representatives etc. to go into the problem of subsidence in the 5
  6. 6. Ranigunj Coalfield AMC has examined 49 unstable localities initially, inJune’92 of which 11 were found to have no apparent danger 21 morelocalities were examined by AMC later in Sept’95 of which one has noapparent danger.In addition to the areas examined by the APEX MONITORINGCOMMITTEE, ECL and CMPDIL have identified 2 more unstableareas. Thus identified unstable areas total to 72. Out of this thepopulation of one site has been rehabilitated. Out of the remaining 71areas, 47 are to be rehabilitated and 24 being densely populated have tobe stabilised.However, out of these 71 areas, 12 have no apparent danger. RecentlyDGMS has indicated 171 unstable localities, which are being examinedin detail by Technical Sub-committee of AMC. The absence of anyproven technology for stabilisation of old inaccessible waterloggedworking indigenous technology of hydro-pneumatic stowing has beenadopted for stabilisation of 5 sites viz. FATEPUR, BORACHAK,HARIPUR, ARUN TALKIES and KUMAR BAZAR.HIGH LEVEL COMMITTEEA High Level Committee was constituted with Secretary Coal asChairman to go into the problem of subsidence & fire in Ranigunj andJharia Coalfield and suggest mitigative measures. The Committeesubmitted its report in January’98. The recommendations of theCommittee were accepted by the Govt. of India and are summarisedbelow(i) Shifting of settlements over unstable areas to non-coal-bearing zones(ii) There should be a total ban on any new construction over declaredunsafe areas. Govt. of Bihar should also enact a suitable legislation in 6
  7. 7. line with the one already existing in West Bengal preventingconstruction over unsafe areas.(iii) Participation and assistance from State Govt. and localadministration is essential. Any enforcing agency entrusted withresponsibilities of carrying out mitigating measures against fire andsubsidence in RCF and FCF should be adequately represented by theabove authorities.(iv) The mitigating measures against subsidence and fire hazards arevery costly options and fruitful implementation can only be possiblethrough separate executing agency with separate funding. Formation andrepresentatives of such agencies responsible for formulating schemes,their implementation and management of funds should be finalised at theearliest. A broad outline of executing agencies has been evolved inconsultation with the concerned State Govt. and the Govt. companies.(v) Hydro-pneumatic stowing technology currently begin used in somelocations in RCF has been found to be a very slow process. High-pressure slurry pumping technology should be tried at some locations inBCCL for stabilising inaccessible unstable underground workings.(vi) Intensive Stabilisation work of unstable areas under locations wherepopulation cannot be shifted like Ranigunj town, should be carried outand persons affected in the high rest but low-density areas may berelocated in a phased manner.(vii) For arranging fund for the purpose of stabilisation and relocation ofpopulation the money could be made available either through plannedexpenditure approved by the planning Commission or unplannedexpenditure from CCDA fund after making suitable enactment.(viii) Considering the urgency one scheme each by ECL and BCCL forshifting of population from unsafe areas may be taken up withoutwaiting for institutional arrangement for funds from planned fundsavailable with Ministry of Coal. 7
  8. 8. (ix) The Interim Reports submitted by BCCL and ECL jointly with Stateauthorities indicating the likely affected population and financialimplications should be kept in mind while drawing up priority-wiseschemes from immediate and effective solutions.IMPLEMENTATION OF THE RECOMMENDATIONS OF THEHIGH LEVEL COMMITTEE1. BCCL has put a total ban on construction of new quarter of on unsafeareas. BCCL is not constructing any houses over coal bearing areas.2. Mining Area Development Authority (MADA) has also issuednotification banning any new construction over critically endangeredareas in BCCL.3. Enactment of suitable legislation banning construction over unsafeareas is still awaited from Govt. of Bihar.4. The District Administration has appealed through local newspapergiving details of the endangered areas of or immediate evacuation,particularly from areas under illegal occupation.5. Govt. of Bihar has been requested to constitute a Sub-authority forrehabilitation of non-BCCL people from endangered areas. This has notbeen done so far.6. BCCL has, as a one-time measure of goodwill, identified arehabilitation city to be handed over to the State Govt. for constructionof 3100 houses for non-BCCL people.7. One R&D project has been started to establish the technology of highpressure stowing at Madhuban Colliery, meanwhile, filling of 8
  9. 9. inaccessible voids is being done presently by hydraulic sand stowingthrough surface bore-holes in many locations in BCCL.EMSC SCHEMESThe schemes under implementation are as under;Subsidence Control Scheme Status1.

Rehabilitation of four 32.52 34012/29/97-unstable locations in ECL CRC dt. 19.5.98While sanctioning these schemes, the EFC allowed release of only Rs.one crore for each of the schemes for initial work. Further release offunds was to be made after recommendations of a committee constitutedby Deptt. of Coal to review the physical progress of implementation ofthese two rehabilitation schemes . The committee, constituted by DOCin Sept99, has submitted the report in Nov99.The status of the implementation of above two schemes, beingimplemented in BCCL and ECL, is given as under: - 19
  20. 20. 1. Progress in BCCL:(I) Present Status:(a) BCCL has initiated action for construction of 1500 houses at 6locations on the non-coal bearing land viz. at Bhimkanali, near KatrasCoal Dump, Bhuli, Nichitpur, East Bassuriya and Amtaal. The workorder was awarded in Sept98. Subsequently, five more work orders havebeen issued for construction of additional houses.(b) 32 Nos. of quarters have been completed at Bhimkanali, 48 units arenearing completion near Katras Coal Dump and 156 quarters are in mid-stage of construction.(c) The process of shifting people from the endangered areas has beenstarted and the first lot of 9 Nos. of old houses in the endangeredlocations of Block-II OCP and 5 nos. at Phularitand have beendemolished completely and 13 families have actually shifted in newlyconstructed houses at Bhimkanali. Shifting activities for the remainingfamilies are in progress.(II) Constitution of Sub-Authority by Govt. of BiharGovt. of Bihar has not constituted the Sub-Authority, so far as per therecommendations of the High Level Committee. A Committee was,however, constituted under the Chairmanship of Commissioner, NorthChhotanagpur, Hazaribagh including Dy.Commissioner, Dhanbad andCMD, BCCL as members. The committee had deliberated on the issueof rehabilitation of non BCCL people during a meeting held on05.09.98. BCCL has offered land for construction of 3100 houses, as aone time measure for rehabilitation of non-BCCL persons.In order to expedite construction of 3100 houses by the Govt. of Bihar, aSub-authority was required to be set up immediately by the State Govt.In this regard, several reminders have been sent since June98 to the 20
  21. 21. Govt. of Bihar. Letters have been sent to Secretary, Mines & Geology,Govt. of Bihar on 22.06.98, 21.07.98 and 25.09.98 for constitution of theSub-Authority. This matter was also discussed by CMD, BCCL with theSecretary and Commissioner, Mines & Geology, Govt. of Bihar on14.10.98.Inspite of the actions initiated by the BCCL, the Govt. of Bihar has notso far constituted the Sub-Authority.(III) Expenditure Incurred or Provision of Funds:An amount of Rs.1.0 crore released by the Govt. of India in 98-99 hasbeen spent by the BCCL for the construction work of 1500 houses.Release of additional funds is in process.2. Progress in ECL:(I) Present Status:Various steps have been taken for implementation in association withthe State Govt. officials for the purpose of finalising the agreement withthe local villagers for shifting of 4 identified unstable areas.
