摘　　要：为了解决矿井煤与瓦斯突出灾害、提高瓦斯抽放率,研制了将高压磨料射流技术与钻孔施工技术相结合的治理煤矿煤与瓦斯突出的新型装备。阐述了该设备的结构组成、工作原理以及防治煤与瓦斯突出的机理。现场应用证明,该设备可以使钻孔内部煤体卸压增透.扩大瓦斯抽放影响范围,有效提高瓦斯抽放率,进而达到防治瓦斯突出,保障煤矿的安全生产的目的。To solve the disaster of coal ＆ gas outburst and improve the rate of gas drainage, the new equipment that combines the techniques of high-pressure abrasive jet and drilling construction is developed. The equipment structures, working principle and the mechanism of controlling coal and gas outburst are expounded. The field application proves that the equipment can make the pressure relief and increase permeability , expand the effective scope of the gas emission, and also improve the rate of gas drainage, so as to achieve the purpose of gas outburst control and the production safety in coal mines.
