摘　　要：随着我国煤炭资源开发逐步向深部发展,巷道地质力学环境日趋复杂,给巷道支护提出了严峻的挑战。针对我国目前巷道支护中存在的主要支护难题,分别论述了高应力巷道、软岩大变形巷道、冲击地压巷道的围岩变形破坏特征,提出了相应的支护对策,并对每种类型的难支护巷道给出了近期研发的典型支护新技术。When coal mining in China gradually extended to the great depth under the surface,the geo-mechanical conditions of roadways were more complicated than ever,and posed severe challenges for roadway support. This paper addressed the typical problems of roadway support in China. The characteristics of rock deformation in roadways with high stress,seriously deformed roadways due to soft rocks and roadways with frequent bumping accidents were analyzed,the adaptive strategies were proposed,and the newly developed support techniques for each typical problem in roadway support were suggested.
