摘　　要：结合孙村煤矿深部大断面岩巷掘进,解决了液压钻车、侧卸式装岩机配套在岩巷掘进的关键技术问题,提出了适用于深部岩巷掘进全断面多重锚喷支护和中深孔爆破技术,实现了大断面岩巷全断面一次打眼、一次装药、一次起爆、一次支护的一次掘进技术,提高了深部岩巷工程质量,掘进速度提高30%以上。With the excavation of deep large cross sectional rock roadway in Suncun Mine, the key technical issues on the rock excavation with the hydraulic drilling jumbo and side rock loader were solved. The paper provided the multi bolt/shotcreting support and medium deep hole blasting technology suitable for the full cross section of the deep rock roadway excavation. The large cross section rock roadway could have a excavation technology with one operation of the bore hole drilling, one explosive material loading, one blasting and one support, which could highly improve the quality of the deep rock roadway project and the excavation rate could be improved over 30 %.
