..............
Chairman further clarified that the specifications of coal reserves available at Thar Coal are duly certified by RWE of Germany, M/s Shenhua of China, Mangolian Institute, United States Geological Survey, etc. He also presented comparisons with world as well as country to country basis. Thar lignite has a stripping ratio of 6:1, heating value of 11-12 MJ/Kg, Ash 7%, Moisture 45-47% and Sulphur 0.9-1.3%. This lignite is suitable for Power Generation and other uses....................]
This original report by John T. Boyd Co. makes for good reading:

2.8
The total in-place seam resources within the study area are estimated to be 19.7 billion tonnes. The associated in-place stripping ratio for the resource is 5.6:1 (bank cubic meters of overburden/interburden : in-place seam tonne). The average cumulative coal zone thickness for the study area is 23 meters.
2.9
Based on available hydrogeological reports for the region and BOYD supervised pumping tests, the coal-bearing formation contains a significant aquifer above Seam Zone A, occasional aquifers between Seam Zones B and C, and a large aquifer below the Seam Zone C. All aquifers in the coal formation are under pressure. Water volumes vary depending on the aquifer. Field conductivity tests indice.te that all aquifers tested are brackish.

Additional drilling is recommended to identify poorer quality areas in Seam Zone A as well as to obtain samples for more detailed coal quality testing.

Pakistan
Proved recoverable reserves (total coal, million tonnes) = 2 265
Production (total coal, million tonnes, 1999) = 3.3
The republic’s coal resources appear to be substantial: The Geological Survey of Pakistan (GSP)
gives measured resources as 3 775 million tonnes, with indicated resources of a further 12 124
million tonnes, inferred resources of 87 366 and hypothetical resources as 81 391 million tonnes,
as at June 30, 1999. The Pakistan WEC Member Committee considers that 60% of the measured
resources should be regarded as proved recoverable reserves.
The discovery of a huge coalfield in the Thar Desert of eastern Sindh province transformed the
country’s coal resources and Thar now contributes 84% of the measured reserves. Under the
auspices of an USAID programme which began in 1985, the field was located in the 1980’s; in the
early 1990’s a drilling programme largely confirmed its extent.
Since issuing the end-June 1997 data quoted in the 1998 WEC Survey, the GSP has reassessed
the allocation of the Thar coal field’s resource base, increasing its measured resources
by 36%, indicated resources by 61% and inferred resources by 30%; overall some 24 billion
tonnes have been transferred out of the "hypothetical" category, whilst maintaining the level of
total resources.
Notwithstanding its massive potential, Pakistan’s coal production in recent years has been only
about 3-3.5 million tonnes per annum. About half is currently produced in the western province of
Balochistan; no Thar coal is produced at present.
Small tonnages of indigenous coal are used for electricity generation and by households, but by
far the largest portion is used to fire brick-kilns. Just over 1 million tonnes of Australian coking
coal is imported each year for use in the iron and steel industry.
