义桥煤矿5302工作面建(构)筑物下开采实践研究

Research on Mining Practice Under Buildings(Structures)in the 5302 Working Face of Yiqiao Coal Mine

义桥煤矿5302工作面属于建(构)筑物下压覆资源,为合理利用该资源,对建(构)筑物下开采进行了相关研究。通过概率积分法对工作面开切眼的位置进行了方案比选,分析了开采后对地表建(构)筑物的影响。结果表明,5302工作面开采方案可行,对地表建(构)筑物影响均在Ⅰ级范围之内。

The 5302 working face of Yiqiao Coal Mine belongs to the overburden resources under buildings(structures).In order to make reasonable use of the resources,the relevant research on mining under buildings(structures)is carried out.Through the probability integral method,the position of the open cut in the working face is compared and selected,and the impact of mining on the surface buildings(structures)is analyzed.The results show that the mining scheme of the 5302 working face is feasible,and the impact on surface buildings(structures)is within the scope of Class I.
