摘要

为了回采巷道的掘进提速和安全使用,煤峪口矿根据14号煤层赋存和顶板岩层特点,巷道掘进时采用了掘进机掘进煤断面、爆破掘进岩断面的"机、炮"结合工艺,成巷速度大增、巷道成型规整;巷道采用U29五节拱形金属棚支护、效果良好,为条件类同巷道施工提供了有益借鉴。
        To speed up excavation and to ensure security of mining roadway,according to occurrence of No.14 coal seam and roof rock features,integrated technique of machine and blasting was used in the roadway excavation(tunnel-boring machine in coal section excavation and blasting in rock section excavation) with increased speed and neat outline of roadways.In addition,U29 five-section arched metal-shelve supporting was used,which has achieved good effects and could be guidance for similar roadway constructions.
