摘要
针对凉山州益门煤矿的煤岩层地质特征,选用矿用U型钢拱形支架来进行该矿的巷道支护。通过理论分析表明矿用U型钢拱形支架在该矿使用是可行的、是行之有效的,在实际应用过程中已取得了良好的社会效益。它填补了四川省松软煤岩层掘进支护的空白。
Directed at geological characteristics of coal formation of Yimen coal Mine in Liangshan, the U-shape Steel mine support section was selected as excavation support in Yimen Coal Mine. Theoretical analysis showed that application of U - shape steel arched support in Yimen Coal Mine is feasible and effective. During the course of practical Qpplication,satisfactory social benefits were acquired. It filled blank of excavation support of Sichuan soft coal formation.
