穿天坡铜矿床位于东川落雪老山与稀矿山之间,长300～420米.五十年代东川大规模勘探时,开掘了四个中段,近二千米坑道.由于地质情况复杂,未开展综合研究,没见矿,做了无矿结论.苏联专家认为:“该地段火成岩不发育,故无矿”;队里也有人认为:“这儿的铜矿转移到铁矿里去了,所以无矿;若是有矿的话,过去打过那么多硐子怎么会一处都碰不到”? 七十年代,我队开展基础地质工作,认真综合研究;打破了“热液论”的束缚,总结出“东川式”铜矿的成矿规律,成功地指导了穿天坡的找矿勘探;使用合理的勘探网度和程度,以水平钻为主要手段,在两年内,以少量的人力、物力、
Chuantianpo copper deposit is located between Dongchuan Lost Snow Mountain and lean mines, with a length of 300 to 420 meters. During the large-scale exploration in Dongchuan in the 1950s, four medium-sized and nearly 2,000-km ditches were excavated. Due to complex geological conditions , Did not carry out a comprehensive study, did not see the mine, made a mine-free conclusion.Sussian experts believe that: “The igneous rock is not developed, so there is no mine”; some of the team also said: “Here the copper transferred to the iron ore went , So no mine; if there is mine, then played in the past so many holes will not touch a place? ”In the seventies, our team to carry out basic geological work, serious and comprehensive study; broke the“ hydrothermal theory ” Bound, concluded the “Dongchuan” copper deposit metallogenic regularity, successfully guided the prospecting exploration days; use a reasonable degree and extent of exploration, with horizontal drilling as the main means, in two years, with a small amount The human, material,
