依据对鹤岗地区煤田地质主要构造的研究,针对鹤岗煤田矿井深部开采巷道支护现存在的问题,提出了巷道支护改进方案,并应用到实际当中。实际应用表明,改进方案有效地控制了巷道两帮移近量和顶底板移近量,解决了煤矿深部巷道支护问题,保证了煤矿的日常生产。 Based on the study of the main geological structure of coalfields in Hegang area, aiming at the existing problems of mine roadway support in deep mine in Hegang coalfield, the improved scheme of roadway support is put forward and applied to practice. The practical application shows that the improved scheme can effectively control the amount of the two tunnels moving closer and the amount of roof and floor moving closer, and solves the problem of deep roadway support in the coal mine and ensures the daily production of the coal mine.
