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,从现场实施效果来看,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.According to occurrence state of a copper ore body, different mining methods are chosen under high temperature and high sulfur pit circumstance. Subsequent filling by sublevel open stoping mining method is optimally chosen for medium-to-thick and steeply inclined ore body extraction, while subsequent filling by explosive transportation mining method is adopted for medium-to-thin and steeply inclined ore body extraction. Structural parameters of these two mining methods are optimized. Field experiments are successfully conducted and good technological and economic indicators are obtained, which provide successful experiences for ore body mining with similar conditions both at home and abroad.
