Abstract：The supporting technology of the transport tunnel in Liuhai Coal Mine and was analyzed the cause of its destruction was summarized through field investigation,laboratory test and theoretical analysis.According to the geological condition,rock character istics and destruction features,deformation mechanism of soft rock was ascertained as swell under high stress,and the supporting technology of flexible layer with rigid gap was put forward.
