| 摘 要： | 针对千秋煤矿暗斜井穿岩巷道的特点、采动对暗斜井的影响状况, 阐述了暗斜井在保护煤柱固定支承压力作用下, 利用拱形可缩性金属支架、锚喷网支护进行一、二次大修的过程。利用围岩有效载荷系数, 解释了暗斜井变形破坏机理, 最后指出了大面积卸压是保持暗斜井长期稳定的经济有效方法, 并给出了卸压开采范围。

| Abstract: | Based on the characteristics of cruts of blind incline shafts of Q ianqiu mine and the affect of mining on the blind incline shafts, the 1st and 2n d major maintenances performed using yielding metal support and bolting and shot creting wire mesh by the effect of their safety pillar's abutment pressure are d escribed. The mechanism of deformation failure of blind incline shafts is explai ned using effective load coefficients of surrounding rock. It is pointed out tha t large area destressing is an economic and effective method, which can keep bl ind incline shafts in stable state for long time and give destressing mining ran ge. |
