主动预防隐伏导水岩溶陷落柱

The active prevention of concealed water karst collapse column

在岩溶发育矿区,导水陷落柱仍然是威胁矿井安全生产的主要因素。如通过合理的手段、有用的水文信息主动预防隐伏在矿井内部的导水岩溶陷落柱,从被动采掘揭露转变为主动探查、发现隐伏导水陷落柱,可避免因被动揭露后造成的水害事故。通过开滦范各庄矿已主动提前发现过几个隐伏导水陷落柱为实例,总结相关经验和办法,为类似矿井主动预防隐伏导水岩溶陷落柱提供参考。

In karst development area, mine safety production was also threatened by conducting water collapse column. Water disaster accidents caused by passive revealing could be avoided through reasonable means. For example, concealed water collapse column could be discovered on the basis of using available hydrological information to active prevention of karst collapse column in the mine and changing from passive mining exploration to active exploration. Taking a few conducting water collapse columns of Fangezhuang Mine discovered in advance as examples, relative experience and methods were summarized, which provided reference to similar mine active prevention of concealed water karst collapse column.
