摘　　要：本文引进了煤层底板抽放巷钻孔抽放、冲孔等综合性措施,有效地增加了煤的孔隙率,提高了煤的可塑性、湿润度和透水性,改变了煤的物理力学性质,较大程度的提高了瓦斯抽放率,解决了措施施工和掘进相集中的问题,为突出矿井的高产高效建设提供了实践经验和理论依据。The liberation of the layer does not have the mining of coal and gas outburst mines, anti - conflict has become an important part of safe production, the paper introduced a coal floor Lane Drainage Drainage Drilling, punching and other comprehensive measures to increase effective coal porosity and improve the plasticity of the coal, moisture and water permeability, changed the physical and mechanical properties of coal, a higher degree of improved gas drainage rate, measures to solve the construction phase and focus on the problem of tunneling, in order to highlight the mine the construction of high yield and efficiency of the practical experience and theoretical basis.
