红透山铜矿是年产50万吨的中型有色金属矿山。主要坑口有三十余年开采历史,开采深度800米左右,矿床系以铜为主的多金属矿床,厚2～30米,倾角50～70度,延深1,100米,矿岩均较稳固。近十几年采用浅孔留矿法和上向水平分层尾矿充填法开采。由于晚期矿山开采条件恶化,对采矿方法的评价、认识、使用比重等问题争论很大,本文试就红矿采矿方法进行经济技术评析,共同研讨。
Hongtoushan copper mine is an annual output of 500,000 tons of medium-sized non-ferrous metal mine. The main pithead has more than thirty years of mining history, mining depth of about 800 meters, the deposit is copper-based polymetallic deposits, thickness 2 to 30 meters, dip 50 to 70 degrees, 1,100 meters deep extension, ore rock are relatively stable. Nearly a decade using shallow hole stay mining method and the level of horizontal tailings filling method mining. Due to the deterioration of mining conditions in late mines, the methods of mining evaluation, understanding, the proportion of the use of a lot of controversy, this paper try on the red mining method of economic and technical evaluation, joint discussion.
