摘要
针对金渠金矿缓倾斜薄矿体全面留矿采矿法开采存在的矿块生产能力低、损失贫化大、安全性差等技术问题,进行了削壁充填采矿法试验研究。详述了试验过程和技术指标,通过矿岩分爆分采、围岩抛掷爆破、充填等技术应用,收到了很好的试验应用效果。
Aiming at the low productivity, poor safety condition and high loss and dilution rate of the breasting - shrinkage method for gently inclined thin orebody in Jinqu gold mine, experiments on waste lifting stoping method are carried out. The experiment process and technical indices are introduced in detail. With separately blasting and stoping of ore and wall rock, walt rock casting blast and backfill techniques, ideal application effects are achieved.
