煤矿井下斜巷上山岩巷掘进一般采用爆破法施工,工艺流程为光面爆破—耙矸机装岩—锚网喷浆支护。传统出矸方式是轨道运输矸石,矸石装车后,绞车牵引矿车运输。该方式效率低,安全可靠性不高。采用刮板输送机和带式输送机运输矸石虽较以前有所改进,但存在频繁延伸刮板输送机和带式输送机的问题,工序复杂,效率提高有限。单一带式输送机运矸方式,可充分发挥胶带连续运输的优势,提高施工综合效率。
Blasting method is generally adopted for excavation of upstate rock drift in inclined shaft of coal mine, and the technological process is smooth blasting - rock-loading rock bolt-anchor net shotcrete support. The traditional gangue way is rail transportation gangue, gangue loading, winch towing tub transport. This method is inefficient and has low safety and reliability. The use of scraper conveyor and belt conveyor to transport waste rock compared to the previous improvements, but there are frequent extension scraper conveyor and belt conveyor problems, the process is complicated, the efficiency is limited. A single belt conveyor gangue way, tape can give full play to the advantages of continuous transport and improve the overall efficiency of construction.
