摘要:根据某铜矿矿体赋存状态,在高温高硫采场的条件下,针对矿体的具体情况选用不同的采矿方法,优化选择中厚以上及急倾斜矿体采用分段空场嗣后充填采矿法,中厚以下倾斜矿体采用爆力运矿空场嗣后充填法,并对两种采矿方法进行了结构参数优化,通过现场实施,试验研究获得了成功,取得了良好的技术经济指标,为国内外类似矿体的开采提供了成功的经验。

Abstract: According to one copper ore body’s occurrence state, at a high temperature and high sulfur pit circumstance, different mining methods were chosen. Subsequent filling by sublevel open stoping mining method was optimally chosen for medium thickness and incline ore body extraction, while explosive transportation mining method were adopted for medium thickness and incline ore body extraction. Parameters were optimized for using these two mining methods. Fie
