院针对鹤煤九矿井下硐室出现浆皮开裂、底臌等类似现象,采用相似模拟的方法,以鹤煤九矿31采区避难硐室临近硐室群实际地质资料为基础,研究分析了给定应力环境下不同支护方式时硐室围岩的变形破坏情况、失稳过程。作者认为,随着顶部压力的逐渐改变,顶板裂隙逐渐增加,裂隙深度和宽度逐步增加,巷道出现离层、底鼓,进而呈现大面积破坏。该结果对区段巷道布置与加固方案优化有一定的参考价值。

The underground chambers of Hebi Coal Company No.9 Coal Mine appear pulp skin cracking, floor heave and other similar phenomena. Based on the actual geological data of chambers near the Hebi Coal Company No.9 Coal Mine 31 mining area refuge chamber, this paper used the analog simulation method to study and analyze the deformation destruction and instability process of rock cavern under given stress environment and different supporting methods. The author believes that with the gradual change of top pressure, roof cracks increase gradually, the depth and width of joints gradually increase, and the roadway appears separation layer and floor heave, and then large area of destruction is showed. The results have certain reference value for the section roadway layout and reinforcement scheme optimization.
