辛置煤矿综采工作面过陷落柱突水机理及防治技术研究

Study on the water burst mechanism and prevention and control technology of fully mechanized working face crossing collapsed coal column in Xinzhi Mine

针对陷落柱突水这一问题,以辛置煤矿2-208综采工作面为工程背景,分析了地下水对煤岩体的影响,并利用数值模拟仿真方法对陷落柱突水机理进行了分析,最后针对陷落柱不同构造情况以及突水情况提出了对应的防治技术,为相似矿井陷落柱突水治理提供参考。

Based on collapsed coal column water burst problem, 2-208 integrated mining face of Xinzhi Mine was taken as an engineering background, the analysis of groundwater on the coal rock body was made, and the use of numerical simulation methods was used to analyze the mechanism of collapsed coal column water burst, and finally the different structural conditions with different corresponding prevention and control technology, which provided reference for similar mine.
