What documents are required for underground coal mining
Technical Support Document For Underground Coal Mining: Rule
Underground mines are classified according to the type of opening used to reach the coal, ie, drift (level tunnel), slope (inclined tunnel), or shaft (vertical tunnel) In contrast, surface mines are mines that are usually within a few hundred feet of the surfaceMr Brian John Lyne, Chief Inspector of Coal Mines, Department Natural Resources, Mines Wa ter, Brisbane (Australia) Ms Wang Sufeng, Director, State Administration of Coal Mine Safety, Safety and health in underground coalminesEach mine requires exploration to prove the resource and then a mine design to define the reserve This mine design cannot be arrived at without a geotechnical assessment which will GEOTECHNICAL EXPLORATION FOR UNDERGROUND COAL The permittee shall emphasize underground coal mining and reclamation practices that will prevent or minimize water pollution and changes in flows in preference to the use of water Underground Mining General Performance Standards eCFR
