    Application of High Strength Polyester Flexible Net in End-mining Holing-through of Shallow Buried Depth of 5.0 m Fully Mechanized Coal Face

    • 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 mine, 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 preparation, transport, construction of lifting anchor cable and other aspects at the period of working face end-mining and holing-through.
