吕沟煤矿是一个生产50多年的老矿井，技术水平和掘进方式都较为落后。岩巷掘进一直是吕沟煤矿生产管理中的重点和难点，尤其是在巷道成形和掘进速度上难以突破并且已经成为了制约矿井生产的重要问题。针对这种情况，在总工程师的牵头带领下，开始在12采区轨道下山进行试验推广“岩巷中深孔爆破技术”以提高岩巷的掘进速度。

Lvgou coal mine is an old mine with a production history of more than 50 years, and the technical level and tunneling method is relatively backward. Rock roadway drivage has been the key points and difficulties in Lvgou coal mine production and management, especially in roadway forming and driving speed, which has become the important problem restricting the mine production. For this kind of circumstance, under the chief engineer's lead, rock roadway deep hole blasting technology began to de promoted in the 12 mining area track downhill in order to improve the drivage speed.
