石菉铜矿是处理高品位难选氧化铜矿石的采、选、冶联合企业。1966年筹建,1972年基本建成,基建投资近1.2亿元。这里仅就露天开采几个问题谈些浅见。一、矿区地质概况石菉铜矿采场是个条件比较复杂的凹陷露天矿,目前开采的东段露天矿属卡斯特洼地次生富集孔雀石矿藏,主要分布在石英闪长玢岩和大理岩附近,埋藏于潜水面以下第四纪残积洪积物中。矿藏呈北西倾向,倾角10°～20°,最大长度1500米,平均宽度为280米,平均厚
Stone green copper mine is dealing with high-grade refractory copper oxide ore mining, election, metallurgical joint venture. Construction in 1966, basically completed in 1972, nearly 120 million yuan in infrastructure investment. Here are some humble views on open-pit mining. I. Geological Survey of Mining Area The stope of Shihchuguang copper mine is a well-conditioned open-pit mine with complicated conditions. Currently, the open-pit mine in the eastern section of the mining is secondary enrichment of malachite deposits in the Custer Depression, mainly distributed in quartz diorite porphyrite and Dali Near the rock, buried in the surface of the Quaternary sediments below the surface. Northwest mineral deposits tend to dip angle of 10 ° ~ 20 °, the maximum length of 1500 meters, the average width of 280 meters, the average thickness
