摘要
在分析蒲河煤矿91采区巷道围岩物理力学特性的基础上,对深部应力叠加区巷道围岩变形机理进行了研究,采用弹性理论计算的方法得出91采区巷道变形规律,并通过相似模拟试验的方法得出深部综放面覆岩垮落结构特征、深部综放面采动影响岩层运移规律,研究成果可为蒲河煤矿91采区巷道支护提供必要的理论依据和技术支持。
On the basis of analyzing the physical and mechanical characteristics of the surrounding rock in the 91 mining area of Puhe Coal Mine, this paper studiedthe deformation mechanism of the surrounding rock in the deep stress superposition area,obtained the deformation rule of the roadway in the 91 mining area by using the elastic theory calculation method, andobtained the caving structure characteristics of overlying rock in the deep fully mechanized caving face and the law of rock migration affected by mining in the deep fully mechanized caving face by the similar simulation test method. The research results can provide necessary theoretical basis and technical support for roadway support in 91 mining area of Puhe Coal Mine.
