开采哲兹卡斯甘矿床时,除主要组份——铜和铅外,还附带回收铼、硫及其他元素。矿床倾斜延伸,使得采矿工艺建筑物相当分散,工业场地占地面积大。矿床部份地段露天开采,使地表遭到大量破坏。由于开采矿石中有用组份的含量相当低,采准巷道工程量大,因此在开采矿床的同时,
In the mining of the Zhezkasankan deposit, in addition to the main components - copper and lead, rhenium, sulfur and other elements are also recovered. Tilting deposits extend, making the mining process quite decentralized buildings, industrial sites, large area. Open-pit mining in some parts of the deposit has caused a great deal of damage to the surface. Due to the relatively low content of useful components in mining ore and the large amount of engineering work required for the entry and exit roadway,
