石(艹录)矿是位于大面积岩溶承压水包围的氧化铜矿.矿石呈黑褐色,粘土、亚粘土状,露天开采.地表深井泵预先疏干,矿坑涌水量大,需施工五十二口大井(终孔直径为377或325毫米),并安装10JD深井泵或潜水泵进行疏干.我们本着自力更生的精神,组成了矿山水文地质队,自己打井、安装并管理生产.几年来完成了四十口大井(武勘帮助完成十五口),每天开动十六台深井泵(排水量62000吨/日),预先疏干采矿工作面,保持了边坡稳定,排出的水又可供应矿山选冶及生活之用.一大井井位的确定疏干大井原则上布在固定边坡10～15米外,围矿湖成半圆形.但由于岩溶发育极为
The mine is a copper oxide mine surrounded by a large area of karst confined water. The ore is dark brown, clay, clay and open-pit mining. Two large wells (final hole diameter of 377 or 325 mm), and the installation of 10JD deep well pump or submersible pump for drainage. We are in the spirit of self-reliance, formed a mine hydrogeology team, dig their own wells, installation and management of production. During the year, 40 large wells were completed (Wuzhan helped to complete 15), and 16 deep-well pumps (62,000 tons of water per day) were started daily to clear the mining face in advance and keep the slope stable. Supply of mining and metallurgy and life. A big well to determine the well Daning well in principle, 10 to 15 meters on a fixed slope, the surrounding lake into a semicircle.But karst development is extremely
