摘 要:富家矿随着开采深度的增加,开采条件发生变化,原来的下向倾斜进路电耙出矿胶结充填采矿法出现了很多问题,诸如:采场出矿效率降低,损失贫化增大,工人劳动强度加重等。应用铲运机出矿下向高分层胶结充填采矿法后,不仅提高了矿块生产能力,减轻了工人劳动强度,而且取得了很好的技术、经济效果。The stoping conditions changed with the increasing mining depth in Fujia mine. And there appeared some problems with the former downward stoping drift electric scraper ore-removal cemented filling mining method, such as lower stoping efficiency, higher loss/depletion rate and labour intensity. With the new carry scraper ore-removal downward high-slicing cemented filling mining method, the ore block producing capacity was raised, the labor intensity was reduced and great economic effects were achieved.
