| 在用平行断面法估算矿产资源量中，对平行断面块段体积参数值计算的精度就决定了其资源量估算成果的精度。在现行 DZ/T 0338. 2-2020《固体矿产资源估算规程第 2部分:几何法》的附录中，对平行断面块段体积( V)的计算规定了:要依据相邻断面形态的差异，需分别选用 4个不同的体积计算公式计算其体积。但是，现发现其中的 3个计算体积公式应用中有时对体积参数值的计算会产生误差，已达到不容忽视的程度。就此文中特推导出 3个新公式来解决该问题，归纳总结出对平行断面块段体积参数计算改进的新方法，以进一步提高其估算矿产资源量的成果精度。 |

| The parallel cross-section method is a traditional method commonly used to calculate volumeparameters. The current DZ/T 0338. 2-2020 " Regulations of mineral resources estimation-Part 2:The geometric Method " appendix C. 4 Calculation clause of parallel section block volume(V)is a summary and inheritance ofthis method. The core of the method is that according to the difference in the shapes of adjacent parallel cross-sectional areas adjacent sections，four different volume calculation formulas need to be used to calculate their volumes. However，it has been found that the improper application of the three volume calculation formulas has ledto the fact that sometimes the calculation error of the volume parameter values has reached a level that cannot beignored，thus affecting the final results of the mineral resource estimate. In this article，three new formulas were derived to address the issue of improper application of existing formulas. A new method for improving the calcula.tion of volume parameters for parallel cross-section blocks was summarized，aiming to further enhance the precision of estimating mineral resource quantities. |
