中条山有色金属公司篦子沟铜矿是一个生产能力一百万吨的大型矿山。其生产探矿方法的演变,大致可分三个阶段。在五十年代末至六十年代中期处于基建时期,是采用坑探进行生产探矿,坑探量占掘进总量的30%以上,由于探矿量大,施工时间长,不仅探矿的费用高,而且采场准备周期也长,采场准备速度落后于采场消亡速度,虽然不断加强掘进力量,也难以适应。
Zhongtianshan Non-ferrous Metal Company Gazi Gully Copper Mine is a large-scale mine with a production capacity of one million tons. The evolution of its production prospecting methods can be roughly divided into three stages. During the infrastructure period from the late fifties to the mid-1960s, production was exploited by pit exploration, which accounted for over 30% of the total excavation. Due to the large amount of prospecting and the long construction period, not only was the prospecting cost high, but also Stope preparation period is also long, stope preparation speed lags behind the demise of the stope, although continue to strengthen driving force, it is difficult to adapt.
