石人沟铁矿在原有单一汽车运输的基础上,因陋就简地于1986年5月建成一条总长2km的胶带排土系统,实现了高排土,少占农田近800亩,同时降低了排土成本。1987年1～8月份共排土130万吨,它为我国中小型露天金属矿胶带排土开创了先例。 On the basis of the original single-car transportation, Shirengou Iron Mine built a tape-drain system with a total length of 2km in May 1986 to achieve high drainage and account for nearly 800 mu of farmland and reduce the cost of soil dumping . From January to August 1987 a total of 1.3 million tons of soil drainage, which for our small and medium-sized opencast metal ore tape to create a precedent.
