Plate 2- Key Plan). • Kasnau Block is approachable by tar road from nearest town Kuchera, located at a distance of 13Km & connected with Nagaur by a hard top road for a distance of about 50 Kms. Nagaur is situated more or less equidistance from jodhpur & Bikaner at a distance of 160 & 165 Kms respectively on Jodhpur-Bikaner state highway. Alternatively, the Matasukh Lignite block is connected with Jayal tehsil head quarter through Farrod village. A Metalled road connects Farrod village to Matasukh block for a distance of 4 km. The Farrod village in turn connects the Jayal tehsil head quarter through Nagaur –Didwana State Highway Road. • The nearest railway station Mundwa, is about 25 Kms.

Email: [email protected] SBU & PC –Lignite Office : Rajasthan State Mines & Minerals Limited KHANIJ BHAWAN, TILAK MARG ‘C’ SCHEME, JAIPUR- 302005 • RSMML presently operates three Lignite Mines, namely: 1. Giral Lignite Mine , Distt. Barmer , 1.0 MTPA , linked to Thermal power Plant of M/s RVUNL- Unit-1, capacity 125 MW at village Giral 2. Sonari Lignite Mine, Distt. Barmer , 1.0 MTPA, linked to Thermal power Plant of M/s RVUNL- Unit –2 capacity 125 MW at village Giral. ii. Brief description of • Lignite is the only solid fossil fuel available in the State and it is nature of the project. prudent to utilize this potential to the best advantage. After analyzing various factors like lignite availability, transport facilities, cost and quality parameters revealed that lignite based power generation offers the most economical option for meeting the power demand in Rajasthan. Lignite is brownish-black in color and has a carbon content of around 17-22%, a high inherent moisture content sometimes as high as 51%, and an ash content ranging from 7% to 17%. Lignite, often referred to as brown coal, is a soft brown fuel with characteristics that put it somewhere. Lignite has a high content of volatile matter which makes it easier to convert into gas and liquid petroleum products than higher ranking coals. Lignite can be separated into two types. The first is lignite or fossil wood and the second form is the compact lignite or perfect lignite. The lignite is single seam deposit and split into two or three sub seams. • Exploration : Kasnau-Matasukh Lignite block is a combination of blocks; namely Kasnau pit in South and Matasukh pit in North, explored by DMG/MECL respectively as under: Block Period of Expln. Agency Matasukh 1987-1992 DMGR July 2002- August 2002 Kasnau 1987-1992 DMGR July 2003- August 2003 MECL Details of drilling carried out by above agencies are as under : Block Period of BH’s Meterage Exploration Expln. agencies (m) 1987-1992 757 7877.30 DMGR Matasukh July 2002- 875.00 DMGR August 2002 Kasnau 1987-1992 1248 15920.88 DMGR July 2003- 965.00 MECL August 2003 Total 214 25638.18 • Exploration report of above blocks was obtained from DMGR. • No. of boreholes drilled within the mining lease area are 214 with overall borehole density of 5/Sq.km. Grid pattern in Matasukh is 200 m x 200 m & in Kasnau is 400 m x400 m. • Details of overburden, inter-burden, cumulative thickness of O.B. (overburden + inter-burden) and thickness of lignite seam are as under : Thickness of Overburden Thickness (in meter) Minimum 42 to 49 Maximum 54 to 105 Average 62.5 Thickness of inter-burden Thickness (in meter) Minimum 4 Maximum 10 Average 7 Thickness of Lignite Seam Thickness (in meter) Minimum 0.2 Maximum 12.00 Average 6.1 • Quality: The quality of lignite based on analysis of core samples obtained during the exploratory drilling, the average quality of Lignite available in this deposit are given below: Moisture % - 48 to 52% Ash % - 5 to 10% V.M.% - 25 to 30% Fixed Carbon % - 18 to 22% Sulphur % - 1 to 2% C.V. Kcal/Kg. - 2800 to 3200 • Geological reserves & Life of Project : Geological reserves of Kasnau-Matasukh lignite mines within the lease area are 33.80 million tonne, out of which 17.29 million tonne are mineable. • The mine is designed for production 1.0 million tonnes of lignite per annum as per the end uses of the lignite mineral. Accordingly life of mine has been worked out:- 1. Overburden excavation over the life: 181 million M3 2. Total extractable lignite reserves: 17.29 million tonnes 3. Initial production for the first five years: 4.86 million tonnes 4. Balance reserves after initial 5 years: 12.43 million tonnes 5. Rated mine capacity: 1.0 MT per annum. 6. Total life of the mine : 20 years. 7. The estimated capital cost of the project is Rs. 210.50 crore only. iii. Need for the project • The Rajasthan state is deficient in power generation. A large gap and its importance to exists between state level generation of power & its demand. The the country and or region state has hardly any known hydro-power potential that can be tapped. Capacity addition from nuclear sources is bound to be slow due to high cost and long gestation period. Under the situation, conventional thermal power plants provide perhaps the best option for bridging the gap. Coal based Thermal Power Plants are less acceptable due to non-availability of coal reserves in Rajasthan state and coal transport over long distance to Rajasthan being difficult and costly, whereas exploitation of available lignite deposits in Rajasthan is expected to be more suitable. • Due to very low sulphur content(less than 2%), the lignite produced from this mine utilized by industries for mercantile usage. • The lignite produced from this mine offers good sources of employment & source of income generation for local people. This project contributes socio-economic development of the region & nation. The project will also contribute to economy by way of royalty, sales tax and additional levy. iv. Demand-Supply Gap • Power is the most used energy form in India. Indeed, it is the fulcrum on which rests the future pace of growth and development. As the tempo of development increases, the demand for electricity also increases.
