我矿是山坡矿床,多中段同时回采,五十年代全用平峒开拓,各中段运输自成系统。六十年代为了减少坑内运输和坑外设施,便于进行集中粗选和排废石,并且使矿山能储备一定的矿量,保证均衡生产,我们经过改造,逐渐形成了初具规模的平峒溜井开拓系统。目前我矿共有溜井10余条,直径最小2米,多为8米,高度一般50米,最高120米左右,每条溜井可储矿300～1500吨,溜井矿石年通过能力目前
Mine mine hillside deposits, mining at the same time middle and more, the 1950s all the peace to open up, the middle of self-transport system. In the 1960s, in order to reduce pit transportation and out-of-pit facilities, facilitate the centralized rough selection and waste-rock disposal, and enable the mines to reserve a certain amount of mines and ensure a balanced production, we have gradually transformed into a first- Open up the system. At present, we have a total of more than 10 chute wells, the minimum diameter of 2 meters, mostly 8 meters, a general height of 50 meters, a maximum of 120 meters, each chute can store 300 to 1,500 tons, chute ore year capacity through the current
