陷落柱突水的防治技术探析

Analysis on Prevention and Control Technology of Collapse Column Water Inrush

岩溶陷落柱的存在容易引起矿井突水,对煤矿正常回采威胁巨大。本文主要探讨陷落柱突水的防治技术,对岩溶陷落柱的形成机理进行了分析,指出岩溶陷落柱的形成需要经历溶洞发育和岩溶塌陷两个阶段,论述了陷落柱围岩特征和陷落柱周边小构造以及陷落柱突水的防治技术。

The existence of the karst real mining in the coal mine is huge. This control technology, the forming mechanism collapse column is easy to cause the paper mainly discusses the collapse mine water inrush, the threat to nor- of karst collapse column are analyzed column water inrush prevention and , and pointed out that the formation of karst collapse column need to experience the two stages of karst cave and karst collapse, and discusses surrounding rock characteristics of the collapse column and the small structure around collapse column and collapse column water inrush prevention and control technology.
