Discussion on Support Problems on Soft Rock Roadway

Advanced Materials Research, 2014
Because of the rapid development of China's coal industry, the average depth of mine increase continuelly, the stress increases obviously, roadway are often difficult to support in many coal mine especially in soft rock. Soft rock have traits of low strength, expansion and rheology seriously, affect the safety of mine production and economic benefits ...
