水溶开采地面沉降的机理分析与控制措施

Study on ground subsidence mechanism of solution mining and control measures

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,探讨了该矿水溶开采后形成的采空区所造成的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意义。

The stability of underground cavern and overburden in the process of drilling solution mining are analyzed and calculated, and so dose the ground surface deformation and movements; the mechanism of the destabilization of cavern and ground subsidence are discussed, some methods for control the destabilization of cavern and ground subsidence are put forward, which can be used for reference in the drilling solution mining.
