摘　　要：本文通过对某矿钻井水溶开采的溶腔稳定性、覆岩稳定性和地表移动变形分析计算,探讨了该矿产生溶腔失稳和地面沉降的机理,并提出了控制溶腔失稳和地面沉降的对策措施,对钻井水溶开采矿山有一定的借鉴价值。Through analyzing and calculating the stability of cavity and overburden rock and moving and distortion of the earth＇s surface due to solution mining in drilled wells in a certain mine,this paper discusses the mechanism which leads to cavity destabilization and ground subsidence,and it also puts forward the countermeasures to control cavity destabilization and ground subsidence, which can be used for reference to mines where solution mining in drilled wells is exercised.
