Thar coalfield
The Thar coalfield is located in Thar Desert, Tharparkar District, Sindh, Pakistan. It contains the sixteenth-largest coal reserves in the world, discovered in 1991 by the Geological Survey of Pakistan (GSP) in collaboration with the United States Geological Survey (USGS). The discovery was the culmination of a coal exploration and assessment programme carried out under the auspices of the United States Agency for International Development (USAID). This programme began in 1985 and formally concluded in June 1993.
Pakistan is regarded as one of the leading countries in terms of coal resources, with lignite coal from eastern Sindh playing an increasingly important role in the national and provincial economy. The economic deposits are mainly restricted to Paleocene and Eocene rock formations. The Thar coalfield covers more than 9,000 square kilometres and is estimated to contain about 200 billion tonnes of lignite, sufficient to meet Pakistan's fuel requirements for centuries.
The Sindh Engro Coal Mining Company (SECMC) is the principal operator engaged in mining activities at the field.
