摘 要:传统上分段凿岩阶段矿房法切割天井的形成,大都采用7655型凿岩机进行浅孔凿岩方式,人员劳动强度大,劳动效率低,且安全上也没有保障,为提高劳动效率,石人沟铁矿采用进口1254台车,进行中深孔凿岩,一次爆破成井,大幅提高了劳动效率,降低了人员劳动强度,提高了安全系数。The traditional method for cutting raise by sublevel chamber stoping is mostly to use Model 7655 drilling machine for shallow hole formation. With this method, the labor intensity is very high, but the labor efficiency is very low and the safety can not be guaranteed. In order to improve the labor efficiency, Shirengou Iron Ore Mine has imported 1254 jumbo to conduct deep hole drilling and form the shaft by one blasting thus greatly increasing the labor efficiency, reducing the labor intensity of workers and improving the safety coefficient.
