摘 要:嵩山煤矿-365西翼轨道运输巷沿L7灰岩掘进,采用光面爆破落岩,原使用气腿式凿岩机施工炮眼,效率低,钻孔方位不易控制,为实现岩巷快速掘进,引进CMJ2-17型煤矿用液压掘进钻车,施工炮眼方位准确,钻眼效率高,大大提高了掘进速度和光面爆破效果,减轻了工人劳动强度。-365 west wing rail transport roadway in Songshan coal mine was excavated along the L7 gray rock. Rock was broken by smooth blasting. Original borehole construction by air-leg rock drill, its efficiency was low, and not easy to control the drilling azimuth. To achieve fast excavation in rock roadway, introducing the CMJ2-17 type coal mine hydraulic drill rig. It can ensure construction borehole's azimuth accuracy, and has high drilling efficiency. Improving the driving speed and smooth blasting greatly and reducing the labor intensity of workers.
