The supporting problems of preparation roadway and gateway have been one of the important research subjects in Chinese collieries. According to the mining condition of the easily spontaneous combustion coal seam in Gengcun Colliery, the authors put forward some concrete measures to control and reduce the roadway deformation of stope raise. Through the reaschering, it is pointed out that the main reasons for the deformation and damage of stoping roadways of fully mechanized sublevel caving mining in the easily spontaneous combustion coal seam are as follows: water accumulating in the bottom stoping roadways caused by the above small collieries mining, basic supports entering into the floor of roadways and the working resistance of the supports decreasing after the surrounding rock of roadways softening. It is considered that the coal roadways should be situated on the surface of coal and rock mutual overlapped seams and the support measures should are strengthen to ensure the regular use of roadways.. The research achievements have been put into the practices of fully mechanized sublevel caving and received expectant effect.
