This study considered the role of coal as China's basic energy source and examines the development of the coal industry. We focused on the intelligent development of coal mines, and introduced the "Chinese mode" of intelligent mining in underground coal mines, which uses complete sets of technical equipment to propose classification …

Mining safety is recognized as one of the factors influencing the mining industry's long-term viability. Therefore, we did a bibliometric analysis to take stock of safety management in the coal ...

Coal Mining 101 – The Coal Seam. The other major form of underground coal extraction is longwall mining. In longwall mines, equipment used in Room and Pillar mining is used to develop two or three parallel entries in a coal seam. The longwall mine entries or headings are usually separated by several hundred feet of solid coal. Aprende más
