深部开采矿井爆破材料库浇筑支护技术

Casting and construction support technology for explosive material supply depot at Deep mining coal mines

口孜东矿属千米深井,该矿-967m水平井底爆破材料库,巷道采用锚网索喷+套棚、注浆支护后进行浇筑施工,主体巷道及炸药壁槽浇筑厚度250mm,以保证达到投入使用标准。

Easter Kouzi Coal Mine is over 1,000 meters deep underground. The roadway of its explosive material supply depot, which is 967 meters under the ground, adopts the bolt, steel mesh, anchor, shotcreting and shed, grouting support before casting construction. The main body roadway and explosive slurry trench, which is cast 250mm thick, ensures the usage standard.
