新城金矿采矿方法和充填接顶工艺探讨

Discussion on Mining Method and Roof-Contacted Filling Technique for Xincheng Gold Mine

为开采新城金矿-480m水平下部矿岩破碎、稳固性较差的V#矿体,开展了开采工艺的技术经济论证,确定用沿走向布置的机械化盘区上向进路充填采矿法,并对充填接顶工艺进行了探讨,该方法在满足生产持续稳定的同时,既解决了与矿山原有系统的衔接问题,又有所创新。

Technical and economical proof was made on the mining technology for the fractured and unstable V^# ore body at -480 level in Xincheng Gold Mine. It was determined to adopt the technology of overhand drift stoping and filling method along the strike in the mechanized panel and the roof- contacted filling technique was discussed. The method can not only satisfy the requirement of a sustained stable production, but also solve the problem of joining with the existing system of the mine with innovation.
