摘　　要：丁集矿埋深大,地压明显,煤层直接顶板节理发育,部分顶板有淋水现象,地温较高,地质条件复杂,巷道围岩蠕变特征明显,巷道掘进困难大,支护困难。为了实现丁集矿复杂地质条件下回采巷道的掘进和支护,以1141(3)工作面运输巷为研究对象进行了试验研究,总结出适合该特定条件下的掘进和支护方式;最后得出巷道的掘进和支护需结合现场地质条件,选择合适的掘进和支护方式,严格按照要求施工,才能取得显著的技术和经济效益。Problems existed great depth, obvious ground pressure ,joints development in coal roof, water drenching in part of the roof, high temperature in Dingji Coal Mine. The creep characteristics of roadways surrounding rock is obvious. It＂ s difficult to tunnel and support the roadway because of the complex geological conditions. In order to realize the tunneling and supporting of mining roadway under complex conditions in Dingji Coal Mine, with the research object of conveyance road in 1141 （3） working face, the method of tunneling and supporting the mine roadway was summarized, which is suitable for the specific conditions. It was obtained that the supporting of roadway tunneling and supporting should be based on the geological conditions ,The remarkable technical and economic benefits can be achieved with appropriate method and strict construction based on requirement finally.
