Exploration and Analysis on Distributed Type Operation and 3D Replacement Mode of Monorail Crane
Three excavation working faces and one stoping working face are arranged in the 3-3 and 4-2 mining areas at the-550 m level in Xiezhuang Coal Mine.The auxiliary transportation method is the main roadway rail locomotive and mining area monorail crane locomotive transportation,the mining areas are connected by rails,and the monorail crane lines are not achieved for networked transportation yet;between monorail crane locomotives and rail transportation,materials need to be transferred and replaced multiple times before being transported to the mining and excavation working face,resulting in low operating efficiency.The cross operation of rail locomotives and monorail cranes requires a large number of auxiliary transportation personnel,and there are many safety hazards.In order to improve the efficiency of auxiliary transportation,Xiezhuang Coal Mine replaces rail transportation with laying monorail crane heavy rails,the monorail crane lines between mining areas are conducted to be networked,"high-power monorail crane+low-power monorail crane"distributed type operation and 3D replacement mode are implemented,achieves fast connection and continuous transportation between the main roadway and monorail crane locomotives of the mining area,reduces auxiliary transportation links and personnel occupation,and improves transportation efficiency,solves the difficult problem of mechanical material transportation for the last 100 m of the excavation working face.
