With the depth of coal mining increasing, in order to solve the problems under geological engineering environment high stress, like rock broken loose, roadway cracking, large deformation, prone to cave, xiandewang mine No.9 mining area pedestrian stone door adopted grouting anchor grouting through shallow hole; deep hole with orifice tube grouting. Cracks caused by crushed rock was filled and bonded, made broken loose rock reform as a whole. The technology thereby reduced the rock loose circle, effectively controlled the cracking, kick drum and roadway deformation problems, ensured the effective cross-section in roadway and greatly reduced the amount of roadway maintenance and the reinforcement effect was good.
