矿体圈定中边界点品位与厚度的内插计算修正公式

在固体矿产矿体圈定中,目前常用内插法的内插计算公式在推导过程中,没有考虑采用最低工业可采品位与最低工业可采米百分率圈定矿体边界的协调性,致使有时不合理地增加或减少部分工业储量。针对这一缺点,本文介绍一个更合理、使用更方便的计算边界点品位与厚度的修正公式。

A CORRECTED INTERPOLATION FORMULA FOR CALCULATION OF GRADE AND THICKNESS AT THE BOUNDARY OF OREBODY

In the delineation of orebody of solid mineral resources, the interpolation method is usually used at present. But the current interpolation formula is inferred without taking it into account that the boundary of orebody delineated through minimum economic recoverable grade should coordinate with that through minimum economic recoverable accumulation, which sometimes results in overestimation of underestimation of economic reserve irrationally. This paper presents a corrected formula which is rational and convinient-to-use, for the calculation of boundary grade and thickness of orebody, directed against the above defect.
