以王家岭煤矿为例,采用数值模拟和现场监测相结合的方法,探索冲沟起伏地貌下煤矿开采矿压显现规律。分别对掘进过程中及工作面回采过程中通过沟谷坡体不同覆岩厚度时巷道的受力及其变形破坏特征进行了研究。并将研究成果用于工业性试验。
Taking Wangjialing Coal Mine as an example, this paper uses the combination of numerical simulation and on-site monitoring to explore the law of underground pressure in coal mining under gully undulation. The forces and deformation and failure characteristics of the roadway during the excavation process and during the mining of the working face through the different overburden thickness of the ditch slope are studied respectively. And the research results for industrial experiments.
