煤仓是矿井运输咽喉要道,关系到矿井生产运输系统的安全高效运行,徐矿集团张双楼煤矿-750m水平西一采区煤仓井壁破裂,局部露筋,锥体露筋严重,钢轨脱落,下漏斗开裂,下沉,漏煤,给煤仓安全运行带来重大威胁,通过拆除原29U圈股、刷扩、锚网临时支护、安装钢井壁及浇灌钢筋砼及壁后注浆充实;锥体及下漏斗整体拆除、并重新整体浇筑等施工,达到安全高效运行的目标。
Coal bunker is the keystone of mine transportation, which is related to the safe and efficient operation of mine production and transportation system. The coal mine shaft wall rupture, partial dew, cone dew, Rail shedding, under the funnel cracking, sinking, coal leakage, to the safe operation of the coal warehouse poses a significant threat by dismantling the original 29U circle shares, brush expansion, temporary support network anchor, installation of steel lining and wall after pouring steel and concrete Grouting enrichment; cone and the overall funnel under the removal, and re-pouring the whole construction, to achieve safe and efficient operation of the target.
