摘　　要：针对我国高瓦斯煤层赋存特点及目前煤矿区域瓦斯治理过程中存在的问题,理论分析了煤与瓦斯耦合作用下爆生裂隙形成机理,开发了新型抽放钻孔密封材料,采用理论研究、数值模拟和现场测试相结合的方式,研究了基于区域瓦斯治理的钻爆抽一体化卸压增透技术,通过控制爆破以及PD复合材料密封抽放钻孔的一体化技术,达到整体卸压、增透、抽放瓦斯和消除突出的目的,并在国内有关矿井进行了应用。According to the high gassy seam features and the problems existed in the regional gas control process of the present mining areas in China,the blasting fracture formation mechanism under the coal and gas coupling role wad theoretically analyzed.A new sealing material of the gasdrainage borehole wasdeveloped.In combination with the theoretical study,numerical simulation and the site measurement,adrilling,blasting anddrainage integrated pressure releasing and permeability improvement technology was studied base on the regional gas control.With the controlled blasting and the PD complex borehole sealing material integrated technology,the targets of the integrated pressure releasing,permeability improvement,gasdrainage and gas outburst elimination were obtained.The integrated technology was applied to some coal mines in China.
