活鸡兔煤矿采煤沉陷危害及地质环境治理

The hazard of mining subsidence and treatment of geological environment in Huojitu Coal Mine

活鸡兔矿区处于毛乌素沙漠和黄土高原过渡地带,生态环境相对脆弱,区内矿井设计规模大,开采强度高,导致形成大面积的采空塌陷区,引发严重的地质灾害和生态破坏。通过生态环境三种治理方法的对比,提出露天剥挖治理法的适用条件,总结出治理的主要工序,实现了活鸡兔矿区生产、生活环境的恢复和改善。

Huojitu Mine is located at the transitional zone between Maowusu Desert and loess plateau. The ecological environment is relatively frail. The high mining strength leads to a large area of ground subsidence and causes serious geological disasters and ecological destruction. Based on the characteristics of mine ecological environment,the open-air stripping method was proposed for the control of goaf subsidence area and the main process was summarized. The research is helpful to the recovery and improvement of the production and living environment in Huojitu mining area.
