我矿目前开采的矿段为一缓倾斜中厚矿体,有上、下两层矿,平均厚度分别为5.78米和3.16米,且区内断层发育,对开采中的贫化损失管理十分不利。为努力减少矿石的贫化与损失,我们从改进采矿方法、穿爆工艺、机械设备、管理与计量等方面入手,取得了一定效果,使近四年的贫损指标均在5％以下(参见下表),保证了较高的矿石质量,
The mine currently mined in the mine is a gently inclined medium-thick ore body with upper and lower strata mines with an average thickness of 5.78 m and 3.16 m, respectively, with fault development in the area, which is detrimental to the management of depletion loss in mining . In an effort to reduce the depletion and loss of ores, we have made some achievements in improving mining methods, blasting technology, machinery and equipment, management and measurement so that the loss indicators for the past four years are all below 5% (see The following table), to ensure a higher ore quality,
