Abstract
In view of the serious deformation problem of the coal seam main roadway passing through the collapse column area in the fifth panel area of Changping Mine,the geological and mechanical parameters of the roadway surrounding rock are mastered through ground stress testing,surrounding rock strength testing,and surrounding rock structure observation.The reasons for the deformation of the coal seam main roadway are analyzed,and a targeted support scheme for the rubber wheel truck roadway passing through the DX176 collapse column in the fifth panel area is designed.The on-site test shows that the overall deformation of the test roadway is not significant,and the anchor cable stress is within a reasonable range,meeting the requirements for the use of the coal seam main roadway,with significant economic benefits.关键词
