| 摘 要： | 烧变岩储水空间开阔，补泄通畅，富水性强，是陕北侏罗纪煤田采煤区特殊而重要的含水层。基于火烧区分布范围、烧变岩物性特征和矿井主斜井涌水特征的研究，总结出其涌水规律。根据井巷布置和涌水特征，认为对烧变岩区煤层涌水的治理应采取井下注浆和地面注浆相结合的方法，并对各种方法在注浆时注浆孔的布局、结构，注浆材料及其配方、注浆参数等进行了详细说明。注浆效果显示：主斜井、1^#副斜井井壁进行壁后注浆处理后．井壁涌水量控制到3m^3／h以下，封水效果明显；3^-1煤中央胶运大巷及辅运大巷进行超前预注浆后，巷道出水量一直控制在50m^3／h以下．从而保证了巷道掘进的正常进行。顺利的通过了火烧区的富水段。

| Abstract: | Burnt rock possesses wide water storage space, open recharging and discharging channels, as well as strong water yield property, thus a peculiar and important aquifer in northern Shaanxi Jurassic coalfield coalmine area. Based on burnt area distribution range, burnt rock physical property and coalmine main inclined shaft water inflow characteristic researches, summed up water inflow regularity. According to workings layout and water inflow characteristics, considered that combined surface and underground grouting should be adopted to control coal seam water inrush in burnt area, and explained grouting borehole layout, configuration, grouting material and formula, grouting parameters in detail. Grouting results have demonstrated that： after wall back grouting, shaft wall water inflow of main and No.1 auxiliary inclined shafts can be controlled within 3m^3/h; after advance grouting the No.31 coal central belt conveyor main roadway water inflow within 50m^3/h all along, thus ensured normal drifting and passed through water rich zone in burnt rock area smoothly. |
