TheKonya-Ilgin-Çavuºçu lignite coalfield is located in the central part of Turkey. This coalfield has been mined in an open-pit manner by private companies. There is a single mined coal seam, the thickness of which varies between 1.10-37.15 m. A total of sixty five boreholes have been drilledin the area toward assessing the reserves. Confirmed and extractable reserves have been calculated by the polygon and isopach methods, depending on the boreholes drilled at different times.

3. Introduction
 The Konya Ilgin lignite coalfield is located in the central part of Turkey (Konya
Province). This coalfield has been mined in an open-pit manner by private
companies.
 There is a single mined coal seam, the thickness of which varies between 1.10-
37.15 m.
 A total of two hundred and eighteen boreholes have been drilled in the area toward
assessing the reserves. Confirmed and extractable reserves have been calculated
by the polygon method, depending on the boreholes drilled at different times.
There is enough coal in the Ilgin coalfield to fuel a thermal power plant.
 The lignite potential of the Konya region, whose coals have low calorific values and
high moisture contents.
While the total confirmed lignite reserve is 447,924,615 tonnes,
Total mineable reserve is 350,857,868 tonnes,
while the total probable reserve is 80,763,455 tonnes
(Inaner and Nakoman 1997).

4. Geology
 The Konya-Ilgin coal seam is of the Pliocene age and its thickness varies
between 1.70–37.35 m. The pre-Neogene** rocks are made up of
Paleozoic metamorphic schists and marbles, and Mesozoic crystalline
limestone.
 The Pliocene* coal-bearing units are made up of basal conglomerate,
gravelly clay, sandstone, coal seam, marl, limestone, red coloured gravel,
sand, clay, and mill.
 All units were covered by alluvium***
 Lignite generally appears as a single seam and is generally quite thick.
Intercalations are rare. The basin is limnic (coal deposits formed inland in freshwater basins,
peat bogs, or swamps).

*Period in the Cenozoic Era ** Geological time period ***loose, unconsolidated soil or sediment that has been eroded,
reshaped by water in some form.

6. Drilling
 In total 218 boreholes have been drilled during 35 years (from 1977-2011) of
which 158 boreholes cut coal thickness.
 The average boreholes depth is approximately 159m and the maximum and minimum
depth are respectively 486m and 13.9m.
 Drill holes which cut coal thickness show the average thickness for coal is 13.36m and
the maximum and minimum are respectively 45.4m and 0.4m.
 The holes which cut coal thickness will be use in calculation.

7. Key Estimation Parameters
 A minimum seam thickness of 0.5m;
 A minimum overburden thickness of 4.0m.
 And Specific gravity of coal of 1.27 tonne/m3
 Resource reporting code
SAMREC Code are is used in this report for mineral resources estimation
1. Indicated mineral resources - estimate is based on limited information
2. Inferred mineral resources - estimate is based on detail information

8. Reource Estimation
 Indicated resource
Having restricted the coal roof and floor surfaces to the border these two are used
to set as upper and lower limits of wireframe(created by gridding) . So, the coal
seam wireframe is determined and coal volume is respectively as 142,999,845 m3
and tonnage is 181,609,803tonnes.
 Inferred resource
By means of this method total estimate wireframe ( created by polygon
method) volume is 145,041,567m3 and total coal resource is 184,202,790
tonnes

10. Project Mining Method
 Based on some auusptions, avialbale geological, enviromental data,
deposit morphology, project budget and social – plitical constrains. It
is concluded that open pit mine method should be use.

11. Mining Method Elements

 Ilgin Coal Project will supply the feed for a thermic power plant. This power plant is
planned to be fed by 4 million tons of coal each year in order to generate the
scheduled electricity.
 The design process for Ilgin pit is developed by Micromine 2014 by using ore body solid
and is not optimized for the bock model and cut off grade, also no economic
optimization and assumption has been taken into consideration. It is assumed that
one the biggest trucks CAT 793 trucks is used for ore and waste haulage.
 Working Bench Geometry
Width of bench: 50 m
Bench Face Slope: 75 degrees
 Ramp
Ramp Width: 30 m
Ramp Slope: 10%

12. Production Schedule
 The mine operates 24 hours a day, 365 days a year. Production
rates vary by material type.
 Currently, ore is scheduled at a throughput rate of 4 Mt/a.
 The total mine life is 45 years as of the end of 2015.
 For the first 5 years and the final pit design and data is given
12

13. Results and discussion
 Mined coal is used for domestic heating and for industrial purposes, especially by
the sugar factories in the region.
 The reserves in this coal field could supply a thermal power plant with a capacity
of 2 × 240 MW for more than forty years.
 Building the thermal power is expected to take about three and a half years, with
2500–3000 workers expected to participate in its construction.
 Additionally, one thousand workers are to be employed in mining the coal
deposit. The power plant is planned as a “build-operate-transfer” model to
produce energy for thirty eight years.
 When this project is finished, it will have positive effects on the Ilgin area, as the
power plant will constitute an important contribution to Turkey’s energy
production.

14. Flaws
 Plagiarism: Basically this report is a plagiarized work of many intuitions and
researchers.
 Not reliable data: Data , diagrams and maps in this report are not reliable and one
cannot depend on this data.
 This report failed to select mining method
 This report failed to do economic analysis
 This report failed to give work plan.
