谢桥煤矿1222(3)W下顺槽提料斜巷上覆于1222(1)工作面下顺槽,下顺槽揭露段55.8m,影响段约112.8m,此段下顺槽采用U29#型棚架棚支护,共170棚。棚档间按“…3333…”型式布置锚索并喷浆加固顶帮。上覆巷道封闭时间久,且与顺槽距离较近,影响区段长,回采压力显现明显,巷道变形大,给安全生产带来的很大困难。为此我们采用了一系列措施保证安全快速通过1222(3)W下顺槽提料斜巷影响段。
Xieqiao coal mine 1222 (3) W under the slot along the feed ramp above the 1222 (1) face down the slot, the next cis-slot exposed section 55.8m, the impact section of about 112.8m, this section under the slot U29 # Shed shelters support a total of 170 shed. Shed file by “3333 ... ” type layout anchor and shotcrete reinforcement top. Overlying the roadway closed for a long time, and close to the cistern, the impact of a long section, the apparent pressure of mining, roadway deformation, to safety production is very difficult. To this end, we have adopted a series of measures to ensure safe and rapid passage of 1222 (3) W under the slot along the slope of the alley influence section.
