摘　　要：结合我国盐矿地质特征和开采现状,对已发生的盐矿地面塌陷案例进行了分析,对涉及盐矿塌陷诱因进行了深入讨论和分析。针对某典型埋深盐矿,采用数值模拟手段量化分析盐矿水溶开采对地面沉降影响。研究表明,对于埋深小于600m的采空区必须避让,对于中深矿体处采空区可进一步论证原址建设可行性。Combined with the geological characteristics and the exploitation status of salt mine in China, the discussion and analysis involving cases of ground collapse in salt mine were carried out, and the reasons leaded to the collapse were discussed and studied. Taking a typical deep salt mine for ex- ample, the influence of solution mining of salt deposit on ground collapse was quantitative analyzed by numerical sim- ulation. The study indicated that the depth of goaf less than 600 m must be avoided, and further demonstrability on imsi- tu construction should be put forward for mid-deep salt goaf.
