为解决澄合矿区复杂结构煤层开采过程中存在的液压支架选型合理性等问题,以该矿区5208综采工作面研究背景,通过现场矿压观测、数值模拟等手段分析研究了矿压显现规律及覆岩的冒落裂隙带发育高度演化特征。其结果为澄合矿区复杂结构煤层综采支架合理性选择以及相似工作面的高效安全生产提供科学依据。
In order to solve the problems such as rationality of selection of hydraulic support in the process of coal mining with complex structure in Chenghe Mining Area, with the study background of 5208 fully mechanized mining face in this mining area, the law of occurrence of rock pressure is analyzed by means of on-site rock pressure observation and numerical simulation And the evolution of the caving fracture zone of overburden. The results provide a scientific basis for the reasonable selection of fully mechanized coal mining supports with complex structures in the mining area and the efficient and safe production of similar work surfaces.
