矿区岩溶塌陷工程治理研究

The Study of Karst Collapse in Mining Area

在覆盖型岩溶区,矿山开采过程中疏排地下水可能导致岩溶地面塌陷。本文基于前人研究成果,阐述了矿区岩溶塌陷形成机理,针对矿区岩溶塌陷成因类型,指出其对应的致灾主因素;分析并探讨了矿区岩溶塌陷工程治理方法及各自的特点与适用性;强调了矿区岩溶塌陷工程治理中几个应注意的问题,指出治理工程宜针对岩溶塌陷致灾主控因素施治,并考虑系统平衡及动态平衡,采取有效的综合治理方案。

Draining ground water during mining often causes Karst to collapse. This paper discusses the forming mechanism of Karst collapse in mining area. Based on the different forms of Karst collapse, it brings forward the main corresponding factors causing Karst collapse. The paper also analyzes the prevention and remediation measures of Karst collapse, including its characteristics and adaptability. In addition, several important questions about Karst collapse remediation are emphasized one by one. Finally, it points out that the Karst collapse remediation scheme should be based on the main factors causing Karst collapse and should take into account the systemic and dynamic equilibrium, so that it should be an integrative one.
