| 摘 要： | 结合孟津煤矿采掘布置及瓦斯地质特性,设计施工1组U形对接井(MS2井组)进行定向掏煤,在地面对煤矿井下目标区进行超前区域瓦斯治理试验。MS2井组共完成4个窗口开窗,L2窗口完成La、Lb2个分支,L3分支卡钻后放弃,其他分支顺利完成,MS2井组累计掏煤300 m3,单支最大长度311.75 m,最大覆盖宽度137.12 m。 |
| 关 键 词： | 突出煤层 U形对接井 定向 水力掏煤,瓦斯治理 |

| Abstract: | A group of U-style intersected wells(MS2 well group) are designed and constructed for directional digging,combined with the digging location of the coal mines and the gas geographic features in Mengjin mine. On the ground the gas control experiment is carried out in the advanced region of the target underground area. MS2 well group has completed a total of four windows fenestration,L2 window has completed two branches of La and Lb,L3 branch gave up after sticking; the other branches finished the work successfully,MS2 well group has dug a total of 300 m3 coals,with the single maximum length of 311. 75 m,and the maximum coverage width of 137. 12 m. |
| Keywords: | outburst coal seam U-style intersected well direction hydraulic coal-digging gas control |
