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。 In order to solve the coal mine and gas outburst disasters and improve the gas drainage rate, a new type of equipment for coal and gas outburst in coal mines was developed, which combines high pressure abrasive jet technology and drilling technology. The structure, working principle and mechanism of coal and gas outburst are described. The field application proves that the device can make the coal inside the borehole to depressurize and enhance the permeability, enlarge the influence range of gas drainage and effectively increase the gas drainage rate, so as to achieve the goal of preventing gas outburst and ensuring the safe production of the coal mine.
