摘要 针对皖北矿区突出煤层群赋存条件,在分析国内现有瓦斯抽采技术适用条件的基础上,研究形成了本矿区典型的井下立体抽采和井上下立体抽采技术,集成了高地应力低透气性突出煤层水力割缝卸压增透技术工艺,得出了适宜矿区的煤矿瓦斯治理技术模式。实践表明,针对性的瓦斯立体抽采模式及工艺技术保证了矿区瓦斯高效治理和煤矿的安全生产。 In view of the occurrence conditions of coal seam group of Wanbei Mining Area, on the analysis of the existing gas extraction technology application condition at home and abroad, on the basis of the research, we formed a typical underground stereoscopic extraction in the mining area and up and down stereoscopic extraction technology for well, integrated technological process of hydraulic slotting pressure of coal seam with low permeability of high ground stress, obtained the technical mode of coal mine gas treatment. The practice shows that the targeted gas stereoscopic extraction mode and process technology can ensure the gas efficient control and the safe production of coal mine.
