Abstract: Aiming at the problem of coal mining in irregular areas of Yushuwan Coal Mine, a double-lane strip mining method is proposed in combination with mining conditions, and its layout, mining method, transportation system, and ventilation system are introduced. According to the shape characteristics of the irregular area of Yushuwan Coal Mine, a plan design was carried out for this area, including layout, roadway specifications and support parameters, main equipment selection, roof management, mining technology, production capacity, etc. Field practice shows that double The strip mining method has greatly increased the mining efficiency of coal resources in irregular areas, and has brought significant economic benefits to the mine. It can be used to recover corner coal resources in mines that use continuous mining machines and shuttle cars to efficiently drive. Actively promote the use.
