摘要 针对我国深部高瓦斯煤炭开采所面临的关键难题,总结分析了目前我国煤矿水力化技术治理瓦斯的研究现状,并指出水力化技术是深部高瓦斯突出煤层卸压增透及区域瓦斯治理的关键技术。通过分析水力压裂、水力割缝、水力冲孔等水力化技术的卸压增透及消除瓦斯突出危险性的机理、技术工艺和工程实践等方面的主要进展,发现了目前水力化技术尚未解决的关键技术问题,并且提出了需待研究的主要内容,为水力化技术的发展指明了方向。 According to the key difficulties faced to the coal mining in deep gassy seam in China, the paper summarized and analyzed research status of the gas control with mine hydraulic technology in China coal mine and pointed out that the hydraulic technology would be the key technology to the pressure releasing of deep high gassy outburst seam and the regional gas control.With an analysis on the hydraulic fracturing, hydraulic slotting, hydraulic punching and other hydraulic technologies of the pressure releasing and permeability improvement and the mechanism, technical technique, engineering practices to eliminate the gas outburst danger and other main progresses, the paper found that the key scientific unsolved problems in present hydraulic technology and provided the main contents to be studied to provide an orientation for the development of hydraulic technology.
