Abstract：In the process of end-mining holing-through and roof management,full mechanized coal face uses metal mesh with hydraulic support is high cost of materials,low efficiency of holing-through and poor safety.With the popularization and use of new materials in the mnine,combined with roof management experience and lessons at shallow buried depth of 5.0 m fully mechanized working face in Bulianta Coal Mine,we summarize the specific requirements and matters needing attention,including high-strength polyester flexible mesh order,material preparatiou,transport,construction of lifting anchor cable and other aspects at the period of working face end-mining and holing-through.
