2019-1-31 In a mining region, during the life period of a mine, large footprints are created. By implementing an effective environmental management plan, mining footprint can be largely reduced. To examine the effectiveness of the control measures, it is essential to use indicators for monitoring of environmental quality of a mine site. Existing indicators have major limitations

2021-10-24 Socioeconomic development is often dependent on the production of mining resources, but both opencast and underground mining harm vegetation and the eco-environment. Under the requirements of the construction for ecological civilization in China, more attention has been paid to the reclamation of mines and mining management. Thus, it is the basement of

2015-8-13 An underground coal mine is a mine at which coal is produced by tunneling into the earth to the coalbed, which is then mined with underground mining equipment such as cutting machines and continuous, longwall, and shortwall mining machines, and transported to the surface. Underground coal mines are categorized as active if any one of the ...

2017-8-1 Xie et al. , proposed that there exists a theoretical limit on mining depth by traditional methods. It is estimated theoretically that all the currently available mining methods will become obsolete once the depth of underground solid mineral resources exceeds 6000 m.Therefore, to realize the development and utilization of mineral resources at great depths, disruptive

Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...
