Turkish Thoracic Journal/Türk Toraks Dergisi, 2015 The underground coal mining, in terms of fatal and injury accidents, has the first place among all businesses due to "spontaneous combustion of coal" and "presence of methane gas" in coalmines. In May 2014, the most casualties (301 people) of recent years occurred in the Soma Eynez mining quarry that accounts for almost half of the death of the last 30

Toward a global coal mining moratorium? A comparative analysis of coal mining policies in the USA, China, India and Australia [PDF]
, 2018 To stop global warming at well below 2° C, the bulk of the world’s fossil fuel reserves will have to be left in the ground. Coal is the fossil fuel with the greatest proportion that cannot be used, and various advocacy groups are campaigning for a ban on

Application and Principle of Bolt-Mesh-Cable Control Technology in Extremely Soft Coal Seam Roadway
Geofluids, 2023 The extremely soft coal seam roadway has the problems of low surrounding rock strength and difficult support. Based on the engineering background of the mining roadway in the extremely soft coal seam of the Quandian coal mine, this paper adopts the ...
