水溶法开采矿山溶腔的扩大可能会引起顶板垮塌，造成井下管柱的损坏，产生的岩层移动波及地表，并导致地表移动与变形。文章在分析水溶法开采矿山特征及回采率设计依据的基础上，分析钻井水溶法开采矿山地表移动的影响因素为采场内承压水的顶托作用、不溶物充填效应、断层的影响、厚表土层对地表变形的缓冲作用等，并从土地流转模式下，允许地表移动与变形量可能发生的变化出发，分析提高水溶开采矿山回采率的依据，然后从提高矿物溶解度和溶解速率、水溶法开采矿山建井措施、采输生产循环方式等方面，探讨提高水溶法开采矿山回采率的措施。

Water soluble method mines of rock-salt cavity expansion may lead to roof collapse, causing the damage of downhole string, the strata movement spread to the surface, and causes the surface movement and deformation. Characteristics based on the analysis method of water soluble mines and recovery rate of design basis, on the basis of the analysis method of drilling water soluble mines the influence factors of surface movement for jacking function of confined water in stope, insoluble ’s filling effect, the influence of fault, and the thick overburden on the surface deformation of cushion, etc. From the land circulation mode, the surface movement and deformation of the possibility have changed. Analysis based on solution mining to improve the recovery rate of the mine , and then from the increase of mineral solubility and dissolution rate , solution mining wells measures to build the mine , mining methods lose aspects of the production cycle , explore measures to improve solution mining mining recovery rate.
