Bolting With Wire Mesh Technology in Complex Geological Conditions Large Section Coal Roadway

With the expansion of the mining scale and production capacity, geological conditions of mine gradually change from simple to complex in Xishan coal mine. There are a lot of high ground stress roadway, large section roadway, soft broken surrounding rock roadway,etc. For the difficulty supported roadway, by narrowing inter-row spacing between the bolt and cable, roadway deformation is still big, which leads to problems of edge tunneling edge repair, high cost of supporting and tense mining-excavation relay.This paper starts from the actual conditions of 62512 roadway and researches the surrounding rock geomechanical testing and support theory and supporting design methods, which ensures the quality of the roadway support and roof management level and solves the problem of roadway support in Xishan Coal Mine Area.
