This is expected to boost coal production and supply in the country. In addition, a Single Window Clearance portal has been launched for the coal sector to expedite the operationalization of coal mines. A Project Monitoring Unit has also been established to assist coal block allottees in ...
In the present investigation, lignite samples from working seams of Matasukh mines, Nagaur, Rajasthan have been subjected to optical microscopy and mineralogy to determine their mineralogical characteristics and paleodepositional condition. Petrographic analysis of composite samples indicates that these ...
The occurrence of methane gas incoal measuresis only too well known because as “fire damp” it is a widespread safety hazard to coal miners. Extensive ventilation systems are required to extract methane from working coal mines. The US Department of Energy has estimated that some 250 MMcf (mi...
“As far as India is concerned, transition away from coal is not happening in the near future,” said Santosh Agarwal, deputy director general at the ministry of coal. “Demand would rise by about 40% by 2030 and only peak in 2040. There would be no closure of mines. Instead, more me...
