矿山采空区稳定性分析及安全治理方法研究

Mine Goaf Stability Analysis and Security Management Method Research

为了加强对采空区稳定性的分析及安全治理方法的研究,结合国内外采空区治理现状,总结介绍了目前常用的采空区稳定性分析方法和安全治理技术,稳定性分析方法方法有岩体质量分级法、安全评价法、块体理论法、预计法及半预计半解析法,安全治理技术有崩落采空区、充填采空区、永久矿柱支撑采空区、隔离与疏通采空区,并对其治理效果、适用范围及实际应用中存在的问题进行了讨论,为不同地质条件下的采空区治理提供了参考。

In order to strengthen thehe stability of goal area safety management methods study, together with the present situation of goaf management at home and abroad, the present commonly used method for analyzing the stability of goal area and security management technology were introduced, the stability analysis method included rock mass quality classification method, the safety assessment method, method of block theory, numerical simulation method, analytical method, estimated method and half expected half analytical method, the safety management technology included caving goaf, goaf filling, permanent pillar support goaf, isolation and dredge goaf, and the treatment effect, scope of application and the problems existing in the practical application were discussed, which provided reference for different geological conditions of goaf management.
