摘要
本文介绍金川镍矿采用机械化下向胶结充填采矿法经过１０年的试验、推广、改革取得的许多经验。由于在采矿工艺、充填工艺、设备维修、劳动工资方面的重大改革，使机械化开采比普通（电耙）法开采劳动生产率提高４倍，开采成本降低２１．９１元／ｔ。
Throush ten year'S testing, application, popularization and reform of downward mechanized cementing back-filling method, Jinchuan Nickel Mine gained rich experince. As a result of the sreat reform of mining art, filling techniques, equipment maintenance and labor cost, the efficiency of mechanized mining was four times higher than that of scraper used usually,and the mining cost reduced by 2. 19/t.
