Analysis of influence range of coal mining on surrounding rock disturbance
-
摘要: 为确定采动过程对煤矿巷道围岩扰动的影响范围及影响因素，对当下煤矿行业的主流扰动监测技术进行梳理总结，基于监测原理及应用效果明确各方法存在的典型问题及后期改进策略；基于微震监测技术对围岩扰动事件的空间分布特征进行系统分析，初步确定采动作用对煤矿巷道围岩扰动影响范围；立足于围岩开采扰动应力重分布、煤层禀赋地质特征、开采方式3个角度探究采动作用对围岩的扰动范围差异性影响。研究发现：结合不同类型监测技术的多参量联合监测手段能够弥补单一监测手段的不足；微震事件分布于沿工作面走向-50~300 m，沿层位方向上煤层顶底板上下-20~40 m范围内；应力重分布与开采方式对围岩扰动的影响集中在工作面向前200 m范围，煤层禀赋地质特征则对工作面向前100 m范围内影响较大。Abstract: In order to determine the influence range and influencing factors of mining process on the disturbance of surrounding rock in coal mine roadway, the mainstream disturbance monitoring technologies in the current coal mine industry are summarized. Based on the monitoring principle and application effect, the typical problems existing in each method and the later improvement strategies are clarified. The spatial distribution characteristics of surrounding rock disturbance events were systematically analyzed based on micro-seismic monitoring technology, and the influence range of mining action on surrounding rock disturbance of coal mine roadway was preliminarily determined. Based on the stress redistribution of surrounding rock mining disturbance, geological characteristics of coal seam endowment and mining method, the influence of mining action on the disturbance range of surrounding rock is explored. It is found that: multi-parameter joint monitoring method combined with different types of monitoring technology can make up for the deficiency of single monitoring method; micro-seismic events are distributed in the range of -50 to 300 m along the strike of working face and -20 to 40 m above and below the roof and floor of coal seam along the horizon direction; the influence of stress redistribution and mining methods on surrounding rock disturbance is concentrated in the range of 200 m before working face, and the geological characteristics of coal seam endowment have a great influence on the range of 100 m before working face.
