摘要
根据大柳矿井11采区上覆岩层的实际情况,采用概率积分法对煤层开采后的地表变形情况进行了预测,绘制了地表下沉等值线图,分析了地表沉陷对周围环境的影响程度和范围,并提出了防治措施,为区内开展类似研究工作和大柳矿井未来生产沉陷的防治提供了参考依据。
Combined with Daliu coal mine overburden 11 mining area actual situation, using the probability integral method, we forecast the surface deformation after coal seam mining, and draw the surface subsidence isoline map and analyze the influence degree and scope of the surface subsidence on the surrounding environment. Based on these work this paper puts forward the prevention measures. It provides a reference for the prevention and treatment of production subsidence in Daliu coal mine in the future. It is also helpful to carry out similar research work in this area.
