摘要
2 0世纪 80年代 ,新城金矿复杂矿体采用沿倾斜分条嗣后一次充填采矿法回采 ;随着无轨机械化程度的提高 ,此种采矿方法暴露出诸多缺点。改进后的采矿方法为平底漏斗式沿倾斜分条嗣后一次充填采矿法。采矿方法改进后降低了采场的损失率 ,缩短了采场的回采周期 ,提高了采场的生产能力 ,获得了极大的经济效益和社会效益。
In 80's,the mining method of stripping along incline and once filling afterwards was adopted in the course of mining complex ore.With the rise of trackless mechanized level,this mining method exposed a lot of defects.The progressed one is flat bottomed tundish stripping along incline and once filling afterwards,It reduced stope loss rate,shortened stope mining period,raised stope productive capacity,gained great economic and social benefit.
