成果介绍中色非洲矿业有限公司谦比希铜矿(以下简称“谦比希铜矿”)西矿体是中色集团接管矿山后新建的第一个矿区,但是矿体赋存于泥质板岩中,矿体下盘主要为砾岩,矿体及近矿围岩层理及节理裂隙发育,易风化,遇水易泥化崩解,矿山地下水丰富,日排水量在10000t/d以上,属典型的复杂难采矿床。自2010年建成投产以来,在生产过程中始终存在巷道及采场垮冒严重,地压显现突出,安全隐患大,严重制约了矿山的安全生产和发展。为
Achievements Introduction Zhongcai Africa Mining Co., Ltd. Chambishi Copper Mine (hereafter referred to as “Chambishi Copper Mine”) is the first new mining area built by China National Metals Corporation after it took over the mine, but the ore body is hosted in the mud In the slate, the ore bodies are mainly composed of conglomerates under the footwall, the ore body and the surrounding rock strata and the joints and fissures of the ore bodies are developed, weathering easily and easy to disintegrate when the water is easy to muddy, the groundwater of the mine is rich, and the daily displacement is over 10000t / d , Is a typical complex hard-mining bed. Since it was put into operation in 2010, there has been a serious collapse of roadways and stopes in the production process. The ground pressure appears prominently and the safety risk is serious, which seriously hampers the safe production and development of mines. for
