煤矿陷落柱水害特征与防治技术研究

 摘要：岩溶陷落柱是我国北方石炭二叠纪煤田广泛发育的一种特殊的隐伏构造。岩溶陷落柱水害是威胁煤矿安全生产的重大灾害之一，充分认识陷落柱的相关规律，对煤矿安全生产意义重大。本文分别从陷落柱形成的基础条件和进阶条件两方面阐述了陷落柱的形成过程；指出了陷落柱分布规律；说明了陷落柱周围局部小构造类型及特征；分析了陷落柱突水机理；明确了陷落柱围岩特征，最后提出了陷落柱的探测方法及陷落柱水害的防治水对策，通过系统的分析，较全面的介绍了煤矿陷落柱水害。

Research on Characteristics and Control Technology of Coal Collapse Column

Abstract: Karst collapse column is a special type of concealed structures developed extensively in the Carboniferous- Permian coalfield in northern China. Water harm of karst collapse column is one of the major disasters which threaten coal mine safety in production. To realize the correlation of the collapse column fully is of great significance to coal mine safety in production. This paper represents the forming mechanism of collapse columns from two sides, one is the basic condition of collapse columns form, the other is elaborated hands-on workshop approach conditions. This paper points out the development and distribution of collapse column explains the types and features of the local small structure around the collapse column, analysis of the mechanism of water harm of collapse column, clears the surrounding rock lithology character of collapse column, puts forward some collapse column detecting methods and proposes of the prevention and control for water harm of collapse column. After systematical analysis, water harm of collapse column is introduced overall.
