在采矿方法中,以充填法、支柱法及支柱充填法的成本最高,采掘强度最低。苏联在有色及黑色金屬矿山,关于充填法的使用,差不多已經絕跡。我国有色金屬矿山中,充填法仍佔很大比重。由于客观情况,在一时还不能停止使用充填法的現狀下,进行現有方法的改进,提高采掘强度、降低成本,是目前的努力方向。我矿地質变化无常、顶板极不稳固,使用留矿法有极大的困难。自1956年年底开始試用水平分层充填法,通过1957年一年的实踐,推广了兄
Among the mining methods, the filling method, the pillar method and the pillar filling method have the highest costs and the lowest mining intensity. In the non-ferrous and ferrous metal mines of the Soviet Union, the use of filling has almost disappeared. China’s non-ferrous metal mines, filling method still accounts for a large proportion. Due to the objective situation, under the current situation that the filling method can not be stopped temporarily, improvement of the existing methods, enhancement of the strength of excavation and reduction of costs are the current efforts. I am a rocky and volatile geological changes in the roof, the roof is very unstable, the use of mineral retention method has great difficulties. Since the end of 1956, the pilot level filling method has been adopted. Through the practice of 1957, a year,
