画眉坳钨矿画眉坳矿区一号副井一期工程已于1979年4月峻工投产。一年多来,运行情况良好。一号副井是矿山自行设计、自行施工的单绳多水平双罐提升盲竖井。井筒位于主矿带下盘的前震旦纪半变质岩系的云母石英片岩与石英云母片岩互层中。绝大多数岩石比较稳固,f=8～10,水文地质条件较好。一期工程联通了375、418,470和 Thyme Au Au Tong thrush mine a mine shaft of the first phase has been completed in April 1979 commissioning. In more than a year, the operation is in good condition. No.1 auxiliary well is a single-rope multi-level two-tank hoisting blind shaft designed and constructed by the mine itself. The wellbore is located in the interbedded layers of mica-quartz schist and quartz mica schist in the Pre-Sinian semi-metamorphic rocks beneath the main ore belt. The vast majority of rocks are relatively stable, f = 8 ~ 10, hydrogeological conditions are better. The first phase of Unicom 375,418,470 and
