针对现有石门揭煤预抽瓦斯煤层增透措施可能诱发煤与瓦斯突出的危险隐患,提出了利用静态爆破技术结合合适的钻孔布置来压裂煤体,增加煤体瓦斯运移通道,提高煤层透气性的技术方法;分析了静态爆破的技术原理、力学过程及现场实施的设计等内容.该方法具有安全、无震动、不产生明火的优点,从而确保石门的安全揭煤.该技术的广泛应用将带来显著的经济效益和社会效益. In view of the potential danger of coal and gas outburst caused by the increase of gas permeability in the prestressed coal seam of Shimen coal seam, the paper proposes to use static blasting technology and appropriate drilling arrangement to fracture the coal and increase the gas passage of coal gas, The technical method of gas permeability of coal seam, the technical principle of static blasting, the mechanical process and the design of on-site implementation are analyzed. The method has the advantages of safety, no vibration and no open flame, thus ensuring the safety of stone door exposing coal. Widely used will bring significant economic and social benefits.
