Concept and Practice of Openpit Mining Area
In the openpit mining process of coal mines, with the gradual excavation of the bottom coal seam, a large amount of coal gangue is generated and piled up near the mining area Coal gangue is wasted and occupies a large amount of land, also, the escape or leaching of sulfide from the gangue will pollute the In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling Appendix E: Coal Mining and Processing 2022年7月26日 Openpit mining is a type of surface mining used to extract coal, gold, and other minerals It creates immense water and air pollution, disfigures landscapes, and destroys habitatsWhat Is OpenPit Mining?
