The Thar coalfield area is covered by dune sand that extends to an average depth of over 80 metres and rests upon a structural platform in the eastern part of the desert. The generalised stratigraphic sequence in the Thar coalfield area is shown in table. It comprises
Basement Complex, coal bearing

The area is accessible by a 410-kilometre metalled road from
Karachi to Islamkot via Hyderabad-Mirpur Khas-Naukot and Thatta-Badin-Mithi-Islamkot. A road network connecting all the major towns with Thar Coalfield have been developed. The rail links from Hyderabad is up to Naukot, which is about 100

As a result of widespread drilling over an area of 9,000 km, a total of 175 billion tons of coal resource potential has been assessed, equivalent to total oil reserves of Saudi Arabia and Iran combined and can be used to produce 100,000 MW for 300 years. Detailed evaluation on four blocks has

The coal beds of variable thickness ranging from 0.20–22.81 metres are developed. The maximum number of coal seams found in some of the drill holes is 20. The cumulative thickness of the coal beds range from 0.2 to 36 metres. Claystone invariably forms the roof and the floor rock of the coal beds.

The Thar coalfield is located approximately between
Latitudes 24°15'N and 25°45'N and Longitudes 69° 45'E and 70° 45'E in the southern part of Sindh Province in the Survey of Pakistan topo-sheet Nos. 40 L/2,5 and 6. Based on available infrastructure and favourable geology, the Geological Survey of

The climate is essentially that of an arid to semi-arid region with scorching hot summers and relatively cold winters. It is one of the most densely populated deserts of the world with over 91,000 inhabitants. The livelihood of the population depends on agriculture and livestock.
479:
The overburden consists of three kinds of material; dune sand, alluvium and sedimentary sequence. The total overburden is around 150 to 230 metres. The roof and the floor rocks are claystone and loose sandstone beds.
267:– The hydro geological studies and drill hole geology shows the presence of three possible aquifer zones at varying depths: (i) above the coal zone (ii) within the coal zone and (iii) below the coal zone.
261:– The water is scanty and found in a few small "tarais" and artificially dug depressions where rain water collects. These depressions generally consist of silty clay and caliche material.
302:
The coal is brownish black, black and grayish black in colour. It is poorly to well cleared and compact. The quality of coal is better where percentage of clay is nominal.

The area is a part of the desert where precipitation is very little with a high rate of evaporation. As such, limited water resources are of great significance.

Pakistan selected four blocks near
Islamkot for exploration and assessment of coal resources. The blocks with names, area and coordinates are given in Table-1:
