Abstract
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, thus the supporting of soft rock roadway engineering has become one of the most complex and the most major problems to solve. By analysising the deformation characteristics of soft rock and deformation characteristics and influence factors of soft rock roadway, We discuss the supporting method and supporting principle of soft rock roadway.
