Practice of Soft Rock Roadway Support in Qingshuiying Coal Mine

Based on the specific geological conditions of coal mine, the factors including the mine exploration and extension methods, the choice and preparation of roadway layers, the roadway layout and density determination, the coal pillar design, the roadway water control, the roadway support parameters determination and the blasting effect control are analyzed. Therefore, technique ways for improving the supporting effects of the soft rock roadway in Qingshuiying Coal Mine are obtained.
