Shuozhou is a typical coal mining city, and the Pingshuo Antaibao open-pit coal mine in its area is one of the largest open-pit coal mines in China. The mi
Japanese trading houses have also become increasing cool on coal, with Itochu announcing plans this month to divest from thermal coal mines by 2024. Thermal coal is burnt in power stations to generate electricity, while metallurgical coal is used to make steel. Vale, which has a hugely profitabl...
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 and grading standards. In view of the basic characteristics and technical requirements ...
doi:10.1155/2022/2892964Water supply prediction and control is one of the key issues in exploitation of coal mine underground reservoirs (CMUR). In order to investigate the water supply for underground reservoirs in coal mines, the aquifers were classified into three types (types I, II, and ...
On the basis of these issues, this study focuses on the coal pillar retention problem of the retreat mining face of the Pinggang Coal Mine in Heilongjiang deep mines. Considering the stress transfer and surrounding rock plastic evolution characteristics caused by coal pillar retention, through ...
the safety risk is a subjective evaluation judgment on an objective basis. Based on many forums with the safety regulation cadres of coal mines at provincial, municipal, and county levels, the experts employed by the supervision departments, the administrative staff of state-owned key mines in pro...
