| 摘 要： | 在介绍石鱼煤矿矿区地质背景条件的基础上，深入阐述了矿区岩溶塌陷的时空分布规律，分析了岩溶塌陷与井下透水在时间、空间上的相关性，进而结合矿区水文地质条件，对岩溶塌陷的成因进行了初步分析。指出矿井透水、淹井、抽水过程中，地下岩溶空间内压强变化是诱发岩溶塌陷的直接因素。

| Abstract: | On July 16th, 2008, in the mining area of Chongqing Shiyu Coal Mine 34 karst collapse pits gradually appeared in the process of flooding, wells flooding and pumping after the flood. On the basis of background conditions of geological environment at the Chongqing Shiyu coal mine, the distribution of karst collapses evoked by underground mining floods in time and space was analyzed. And the correlation between karst collapses with the hydrogeological conditions of mining, the causes of karst collapse were analyzed. At the end, this paper proposed that pressure changes of karst underground space is the direct factor inducing karst collapse in the process of coal mining flooding, flooded wells and pumping. |
