铜录山矿露天与井下 综合防治水技术 铜录山铜铁矿是鄂东塌陷最发育的地区之一,十余年来,先后产生大小塌洞192个,最远的塌洞发展到距矿坑约2000m处,塌洞密度每一百平方米达65.7个,1981～1933年青山河多次断流,河水通过塌陷区灌入地下,地面塌洞增加到320个。靠单一的疏干排水方法已无法解决该矿的环境地质问题,因此,采用以注浆帷幕截流为主,辅以对青山河及塌陷区的整治。1988年以来,长沙矿山研究院和大冶铜录山铜矿联合开展了大型注浆帷幕截流和坑内排堵综合防治的研究工作,历时4年半,
Tonglushan mine open-pit and underground comprehensive prevention and control of water technology Tonglushan copper-iron ore is one of the most developed areas in eastern Hubei subsidence, more than 10 years, has produced a total of 192 cave-sized cave, the farthest cave developed into the pit At about 2000m, the density of collapsed holes reached 65.7 per 100 square meters. During 1981-1933, the Qingshan River discontinued several times and the water poured into the ground through the subsidence area. The number of collapsible holes on the ground increased to 320. By means of a single drain dry drainage has not been able to solve the environmental geological problems of the mine, therefore, the use of the closure of the main grouting curtain, supplemented by Castle Peak River and subsidence area renovation. Since 1988, the Changsha Institute of Mining and Daye Tongluoshan jointly carried out a large-scale grouting curtain closure and comprehensive prevention and control of pit drainage research work, which lasted 4 years and a half,
