通过采取选择合理位置布置巷道、避开矿压峰值区、控制顶板、下压式松帮卸压、喷顶式松帮卸压、打眼式松帮卸压和煤岩层注水固化煤岩体等技术措施,在“三软”煤层工作面的掘进和回采过程中,有效防止了煤壁片帮、冒顶,减少了支柱下沉量,降低了工人劳动强度,工程质量明显得到改善,保证了安全生产。 By choosing the reasonable location of the layout of the roadway, to avoid the peak pressure mine area, roof control, pressure relief loose pressure relief, roof loose loose relief, drilling loose loose relief and coal seam rock solidification technology In the process of tunneling and recovery in the “three soft” coal seam face, the coal wall slice prevention and roof caving are effectively prevented, the pillar subsidence is reduced, the labor intensity of workers is reduced, the quality of the project is obviously improved, Safe Production.
