Thar caol as Alternate source of Energy

  1. 1. Feasibility of Coal Mining in Thar“An alternate source of Energy” PRESENTED TO: DR. ZULFIQAR AHMED BY: MUHAMMAD YOUNAS Compiled and Acknowledged By: MAJID KHATTAK Department of Earth Sciences QAU Islamabad. Email: majidqau@live.co.uk Cell No: +923459288637
  2. 2. Thar Coal Field Location Map 2
  3. 3. Geology of Thar• The Thar coalfield area is covered by dune sand that extends to an average depth of over 80 meters and rests upon a structural platform in the eastern part of the desert. The generalized stratigraphic sequence in the Thar coalfield area is shown in table. It comprises Basement Complex, coal bearing Bara Formation, alluvial deposits and dune sand. 3

  5. 5. Hydrogeology of Thar The hydrogeology study examines the effects of surface water and groundwater on the mining site. There are no rivers or significant water courses on the mine site or adjoining lands and there are only significant rains in the monsoon season when surface run off will have to be managed. There are 3 aquifers within the mine site which will require dewatering to enable the mining to proceed to the base of the pit. There is an intermittent aquifer at the base of the upper dune sands which does not contain significant volumes of water. www.sindhcoal.gos.pk 5
  6. 6. • A second aquifer is located in the Bara Formation above the Lignite and extends throughout the coalfield. Again it does not contain significant volumes of water but will require dewatering in advance of excavation to maintain the stability of the pit walls.• Below the base of the Lignite and confined by the basal granites at depth there is a major aquifer which again extends throughout the coalfield and requires lowering to below the base of the pit to prevent floor heave and other instabilities at the lower levels of the mine. 6
  7. 7. • All the waters in the aquifers is slightly saline or brackish and would require treatment for drinking or irrigation and a Reverse Osmosis plant will be constructed to provide the same 7

  9. 9. Coal’s Significance in Global Energy Scenario  Global energy consumption will rise by 50% by 2030. In non-OECD region, it will rise by 85% (International Energy Outlook Report 2008)  Coal use is likely to grow from 40% to 44%, as a source for power generation, by 2030* due to energy security and price volatility.  Besides use in power generation, various countries have initiated projects to produce Coal-to-Liquids, that entail producing diesel and other liquid products and Coal gasification projects in China, US, India and South Africa.  World Proven Coal Reserves – Over 860 billion tons.* Source IEA Report 2009 9

  17. 17. Benefit to Economy – Reduction in Power Generation Cost• NPV of savings from Block II alone is over Rs. 3.2 Trillion
  18. 18. Annual Savings in Foreign Exchange from Thar Block II• Cumulative savings of over USD 87 Billion from Block II alone
  19. 19. Vision for Thar Coal“To develop Thar Coal as a major source of power generation for Energy & Economic Security of the country and as a Hub of Petro Chemical Industry” Goal To generate at least 10,000 MW by 2020 19
  20. 20.

  23. 23. Investment Options1. Coal Mining Investors interested only in mining may applyfor a mine lease for mining the coal.2. Integrated Coal & Power Generation Project Investors may also opt for investing anintegrated coal mining and power generationprojects.3. Mine Mouth Power Project Thar coalfields present best opportunity formine mouth power projects in view of the greatdemand for energy in the country. 23
  24. 24. Investment Options4. Coal Gasification Investors may propose to convert coal into gas and market the syngas and bye products in open market, or may develop a forward integrated project on any one or more bye products from gasification project5. Coal to Liquid Projects Investors may propose to convert coal into Liquid and market the byproducts in open market, or may develop a forward integrated project on any one or more bye products from CTL project 24
  25. 25. Conclusion• It is clearly established that Thar Coal has immense potential, not only to meet Pakistan’s primary Energy requirements for Power generation (IGCC, CCPP), Transport fuels (CTL, FTD), Natural gas (SNG), fertilizers, petro chemicals etc ramping up from 2012 to 2030, but sufficient quantities can be produced for bridging the gap in Asian Energy markets.• Thar Coalfield has not been developed due to incorrect project development approach, which has been based on one, or two 1000 MW power plant set-up. 25
  26. 26. Continued……….• It is essential that a new modality be followed now and a Master Plan be prepared, for full field development and downstream multiple applications based on highest economic returns.• On successful demonstration of a production mine with proper engineering, mining methodology and analysis of bulk samples, a full Thar coalfield development bankable feasibility and Master Plan will be prepared to undertake the multibillion dollar project in phases from 2010-2030 26
