    THE RESEARCH ABOUT GROUND FISSURES CHARACTERISTICS AND MECHANISM OF JINGERQUAN MINING

    • 摘要: 金属矿山地下开采引起的地裂缝问题已成为一种严重的矿山地质环境灾害,受到越来越多的关注。镜儿泉矿区经过前期的浅孔留矿法开采产生了大范围的地面塌陷和地表裂缝,后又采用充填法开采以保障地表建筑物的安全。本文以现场调查和地表GPS监测数据为依据,从地表裂缝的形成和发展探讨了地裂缝的分布特征、变化规律和形成机制。研究结果为保障矿山的生产安全提供了依据。

       

      Abstract: Metal mine ground cracks caused by underground mining become a serious of mine geological environment problems and appeal more and more attention. Jingerquan appeares quantities of ground fissures and lager area of ground collapse because it adopted short-hole shrinkage method in the early time. Afterwards, back filling method was adopted in order to protect from collapsing the building around the mining area. Based on the actual reconnaissance survey and long-term ground GPS monitoring data, the changing rules and formation mechanism of ground fissures are discussed from the forming and developing trend of surface crack. This article provids theory basis for the safety of mining production.
