| 中文摘要: |
| 地质块段法是现在固体矿产勘查工作中最常用的方法。地质块段法一般是用块段的平均倾角和块段投影面积换算得真面积,用块段真面积和块段矿体平均真厚度计算矿体的体积,再与矿石体重相乘而得矿石量。块段的平均倾角是统计得来的,在矿体产状变化极大,平均倾角误差大,甚至无法统计的情况下,会导致资源储量估算误差很大。建议用块段平均铅重厚度与投影面积计算矿体体积,这样估算的资源储量误差相对更可靠。 |
| 英文摘要: |
| Geological block method is common method applied in the solid mineral exploration work. The principle of geological block method is that the true block segment area is converted based on the projected area and average dip angle of block segment, then, the volume of orebody is calculated based on the true area size of the block segment by multiplying the average orebody thickness of block segment, and the ore tonnage is calculated by orebody volume multiplying ore density.The average dip angle of block segment is based on statistical result. In some case, the average inclination error occurs when the attitude of orebody varies greatly, which will result in big error of reserves estimation. It is recommend that the volume of ore had better is calculated by an average verticalline thickness of segment block and projected area, then the estimated reserve estimation relatively more accurate. |
