摘　　要：煤矿开采最容易引发的地质灾害便是地面塌陷。为了准确反映出采煤带来地表移动和由此产生采空区地面塌陷范围变形的整体全貌,本文以甘肃省白银市某煤矿为例,采用国家有关部门近年推荐的并且在生产应用中较成熟的“三下规程”,利用充分采动条件下多煤层多工作面概率积分法预计软件和等值线绘制程序对该煤矿进行了地面塌陷预测。根据预测结果,对地面塌陷可能造成的影响程度及危害性进行了分析;通过总结历史治理经验,提出了综合防治措施建议,为矿山进一步开展地面塌陷治理提供了参考依据。The most common geological disaster caused by coal mining is ground collapse.In order to accurately reflect the overall picture of surface movement caused by coal mining and the resulting goaf ground collapse deformation,this paper takes a coal mine in Baiyin City,Gansu Province as an example,and adopts the"three rules"recommended by relevant state departments in recent years and relatively mature in production and application.The ground collapse prediction of this coal mine is carried out by using the prediction software of probability integral method of multi-coal seam and multi-working face under full mining conditions and the program of isocontour drawing.According to the predicted results,the influence degree and harm caused by ground collapse are analyzed.By summarizing the historical treatment experience,the comprehensive prevention and control measures are put forward,which provides a reference for the further development of ground subsidence treatment in mines.
