摘要
赤峰红花沟金矿根据多年人工底部结构施工经验，利用挑顶后崩落的矿石作为临时支护，直接在其上部浇注钢筋混凝土的假底施工工艺，取代了木棚子支护后浇注钢筋混凝土工艺，加快假底施工速度，节约了原材料，降低成本，提高了经济效益．
Based on rich construction experiences of many years,Chifeng Gold Mine tubes the fallen ores after roof cutting as preliminary support instead of timber set,then pouring reinforced-concrete on their top to construct artificial sill.This accelaratot the speed of the construction of artificial sill while saving raw and semifinished materials and lowering production cost. As a result, the economic benefit is enhanced greatly.
