FX24断层防隔水煤(岩)柱安全评价及工程实践

Safety evaluation and engineering practice of water resisting coal(rock)pillar in FX24 fault

通过含水或导水断层防隔水煤(岩)柱的经验公式、“下四带”理论的分析计算,确定了FX24断层防隔水煤岩柱的尺寸,同时通过物探和钻探手段对5302工作面水文地质环境进行验证分析。5302工作面的安全顺利回采证明,该论证方法科学合理,具有很强的指导意义。

s:The size of FX24 fault water proof coal(rock)pillar is determined through empirical formula of water bearing or water conducting fault water proof coal(rock)pillar and analysis and calculation of"lower four belts"theory.At the same time,the hydrogeological environment of 5302 coal face is verified and analyzed through geophysical exploration and drilling methods.Safety and smoothly mining of 5302 coal face proves that the demonstration method is scientific and reasonable,and has strong guiding significance.
