榆神矿区某煤矿条带开采引发地面塌陷变形程度简析
|
摘要
煤炭资源的开发利用会造成含水层结构破坏导致地下水渗漏、诱发地面塌陷破坏土地资源等一系列地质环境问题。根据榆神矿区某煤矿通过条带垮落法开采3号煤层实现保水采煤这一特性,通过多种方法综合确定了3号煤层采动影响下的地表移动与变形各主要参数数值。然后运用概率积分法,对条带垮落法开采后引起的地表移动与变形程度最大值进行了预测分析,为矿山实施地质环境保护与土地复垦等提供参考和依据。
The development and utilization of coal resources will cause a series of geological environmental problems, such as the destruction of aquifer structure, the leakage of groundwater, the collapse of ground and the destruction of land resources.According to the characteristics of a coal mine in the Yushen mining area mining the No.3 coal seam by the strip mining method to realize the water-containing, the main parameters of the surface movement and deformation under the influence of the mining of No.3 coal seam are comprehensively determined by various methods. Then, using the probability integration method, the maximum value of surface movement and deformation caused by strip mining method is predicted and analyzed,which provides reference and basis for the implementation of geological environment protection and land reclamation.
