摘要
随着我国国内采用水溶法开采盐矿的普及,地面沉降地质灾害屡屡发生.因盐矿地面沉降一般具有持续周期长、影响规模大、破坏性大、突发性强、反复发生、发生前后通常伴随地面冒卤等特点,总结后发现采空区造成溶腔顶板失稳、岩石节理裂隙或断层发育、溶腔顶板岩体承载力低是水溶开采诱发盐矿地面沉降的3种主要因素.主要从事前预防、事中控制以及事后补救这3个方面提出了相关的地面沉降治理措施建议.
Abstract
With the further popularization of using the water-solution method to mine salt mines in China,geo-logical disasters caused by ground subsidence have also occurred repeatedly.Due to the characteristics of the long duration,large impact scale,high destructiveness,strong suddenness,repetitive occurrence and ground brine before and after occurrence,and it is concluded that the instability of the solution cavity roof,the development of rock joint cracks or faults and the low bearing capacity of the solution cavity roof caused by goaf are the three main fac-tors of the ground subsidence of salt mines induced by water-solution mining.This article puts forward suggestions on ground subsidence control measures from three aspects:beforehand prevention,in-process control and ex-post remediation.
