湖南某煤矿地区岩溶塌陷成因机制分析

The Cause Analysis of Karst Collapses in a Hunan Coal Mine of Hunan Province

随着经济的发展,人们对矿产资源的开采量不断增大,在其开采过程中对地质环境的破坏也愈发严重,各类地质灾害伴随而来,给人民的生命财产安全及社会经济发展带来不利影响.综合考虑水文地质单元、灾害发育程度、地层岩性、地质构造及矿山抽排水等因素,结合岩溶发育规律,对煤矿区内岩溶塌陷的成因机制分6个区来进行了分析,得出岩溶发育与矿井大量抽排水是该地区岩溶塌陷发育的最重要原因,研究成果可为该区域内岩溶塌陷的主要发展趋势预测和预防治理提供依据。

With the economy development at a faster speed, there is an increasing demand for mineral resources, which leads to not only the serious destruction to the geological environment and the simultaneous geological dis- asters, but also adds the adverse effects to people＇s lives and assets as well as to our social and economic develop- ment. With in mind the factors such as the hydro geological units, the degree of disaster development, formation lithology, geological structure and mining pumping drainage, etc, this paper makes an effort to analyze the cause of karst collapse in six zones in the coalmine to conclude that karst development, large - scale pumping and drainage are responsible for the karst collapse. What is found in this research can provide a reference for the pre- vention and control of geological disasters in this region.
