摘要
结合三山岛金矿新立矿区开采特点和生产实际,根据当前的开采技术条件及经济技术指标,改变了边界品位指标,计算了品位指标变动后的各级储量,并对边界品位指标变动后的经济效益进行了概算。边界品位的变动及开采实践表明,新立矿区不仅充分回收了低品位资源,而且取得了显著的社会效益和经济效益。
Combining with the mining features and production practice in Xinli mining area of Sanshandao gold mine, the limiting grade is changed based on the current mining technical conditions and economic and technical indices. The different levels of reserves are calculated and the economic benefits are generally estimated after the grade changes. The mining practice show that not only the low-grade resources are recovered but also good social and economic benefits are obtained.
