向山硫铁矿已有三十余年开采历史。过去曾使用过分层崩落(分层高2.5米)和低分段崩落(分段高4.5米)采矿法。 一九六四年,在上级党委的亲切关怀下,在矿党委直接领导下,组成了试用新采矿法的三结合小组,并得到马鞍山矿山研究院的大力支持,试验推广了无底柱分段崩落(分段高7.0米)采矿法,配备了华—1型电动装岩机(后改革为距控装矿),成功地解决了端部装矿机械化问题,使采矿工人从笨重的体力劳动中解放了出来,这是我矿采矿生产上一次具有深远意义的变革。 Has more than thirty years of mining history to the mountain of pyrite. In the past, subsoiling (stratified 2.5 m) and low-subsidence (4.5 m high) mining methods have been used. In 1964, under the cordial concern of the party committees at the higher level, under the direct leadership of the coal mine party committee, a triad of new trial mining methods was formed and supported by the Maanshan Mining Research Institute. Caving (7.0 meters tall) mining method, equipped with a -1 type electric rock loader (after the reform for the control of ore loading), successfully solved the mechanization of the end of the mine, mining workers from bulky manual labor Was liberated, which is the last significant change in mine production.
