凹陷开采石灰岩矿引发岩溶塌陷的防治浅论

Prevention and control of karst collapse caused by limestone mining in the depression

岩溶塌陷是我国岩溶地区常见的地质灾害,凹陷开采石灰岩矿由于在矿坑内抽排地下水,可能引发或加剧矿区及周边的岩溶塌陷,本文以湛江某石灰岩矿为例,探讨分析岩溶塌陷的特征及成因,提出对凹陷开采石灰岩矿引发的岩溶塌陷的防治思路。

Karst collapse is a common geological disaster in karst area, deep mining limestone mine pit due to the pumping of groundwater, karst may cause or exacerbate the mining area and the surrounding land subsidence in Zhanjiang a limestone mine as an example, to explore the characteristics and causes of karst collapse and puts forward prevention ideas lead to the exploitation of limestone karst depression mine collapse.
