摘要
针对齐家沟矿区燕山矿段倾斜～急倾斜极薄矿脉,深部矿体倾角变缓、矿岩稳定性变差等特点,通过将削壁充填采矿工艺与上向水平分矿尾砂胶结充填采矿工艺结合与试验,解决倾斜～急倾斜极薄矿体贫失两率大、矿块生产能力较低的实际问题.
Abstract
In view of the characteristics of the inclined to steeply inclined extremely thin ore veins in the Yanshan section of the Qijiagou mining area that the dip angle of the deep ore body is slowing down and the stability of the ore rock is deteriorating,the practical problems of large dilution and loss rates of the inclined to steeply inclined extremely thin ore veins and low production capacity of ore blocks are solved by combining the mining technology of resuing and filling with the mining technology of upward slicing and cemented filling by tailing.
