| 大比例尺矿床统计预测中,矿产资源量的估计是矿体定位预测的前提,其中精度最高的方法是体积估计法。文章借助实例分析,对体积估计法的计算程序进行了阐述。以区间概率解析法对矿脉和矿化体在垂向空间的金品位进行分解,解析出其金品位统计分布模型;利用波形分布模型对深部盲区进行预测,对各中段的金品位、矿化体体积、矿石在矿化体中的体积分数进行解析和计算;并利用有效探矿指数进行合理的校正,最后得到近似于地质储量的金矿产资源量,为下一步的矿体定位预测提供定量数据。经计算该矿重点预测区(-290m～-810m标高)预测的有效金矿产资源量为70.28t,经部分工程控制,已获D+E级金储量18t。 |

| In large scale statistical prediction of Au ore deposits mineral resource estimation is the prerequisite for location of the predicted ore bodies. Volumetric estimation method is the most accurate one. Here is the description of the calculation procedure. The interval probabitity analysis method is used to analyse spatial distribution of Au grads of ore bodies and mineralized bodies in the vertical direction and obtain the statistical distribution model. The wavy distribution model is used to make prediction at blind areas. Au grade, volume of the mineralized bodies, ore percentage of the mineralized bodies are calculated for all levels. The results are calibrated with the effective ore exploration index to give mineral resource volume aproximate to geological reserves. The data is used to location of the predicted ore bodies. For example, 70.28 t of effective mineral resouce for a gold mine is predicted and 18 t of reserves (D+E) has be located by the uncompleted explorational engineerings. |
