| 中文摘要: |
| 八卦庙金矿床的主要特点是金矿规模大、品位低,矿化主要集中在东西长300~500 m,南北宽300~400 m的斑点状千枚岩中。矿化的分布特点是:围岩—矿化体—矿体,品位呈逐渐过渡关系。随着矿山生产规模的扩大和金价的上涨,从矿山开采实践来看,开采金品位1.5×10-6的矿石有良好的经济效益,降低工业指标,能扩大资源储量,对充分利用资源,延长矿山寿命都有重要的作用。 |
| 英文摘要: |
| Baguamiao gold depositis characterized by large scale and low grade. The mineralization concentrate in the spotted phyllite with 300~500 m from east to west and 300~400 m width from north to south. The overall distribution of the mineralization from the surrounding rock to ore body is gradually varied in grade. Along with the enlarging scale of the production and the rising gold price, according to the practice in the past, it can bring the significant economic value to develop the gold ore with 15×10-6 grade. Decreasing the industry index can enlarge the resources and reserves, and these actions are both important to fully use the resources and extend the mine life. |
