以深部突出危险性强的首采层和不具备保护层开采条件下的单一低透突出煤层瓦斯高效抽采为立足点,基于煤矿井下瓦斯抽采存在的问题,引出并定义了煤矿井下水力扰动抽采瓦斯技术。以"精细地质设计优化、钻压冲修扰动强化、封联抽排工艺细化、瓦斯抽采评价量化"为技术主线提出了煤矿井下水力扰动抽采瓦斯技术体系,重点介绍了其10项核心技术及装备的作用、特点及现场应用情况。针对该技术体系在基础理论、卸压增透核心技术和配套装备存在的问题,认为精细化抽采地质分析和单一低透煤层煤与瓦斯共采模式基础理论研究、卸压增透核心技术的完善与集成和配套装备的系列化和智能化是今后技术体系完善进程中的研究重点。

Based on the deep first mining seam with the outbourst danger and the high eficient gas drainage from a single ow permeabilty and outburst seam as afoothoid under the condtton of the mining without a protective layer and based on the problems existed in thegas drainageof the underground mine a hydraulic disturbance gas drainage technology in the underground mine was introduced and defned.Based on a fine geologicaldesign optimization. ling pressire an fushing repair dsturoance emhanced and gas crainage evaluation quanttative as the technical main line ,a hyraulc disturbance gas drainage technology system of the underground mine was provided.
