山西西里北铁矿矿体资源储量估算中斜楔形体积公式的应用

Application of Skew Cuneiform Volume Formula in Reserve Estimation in Xilibei Iron Deposit in Shanxi Province

斜楔形体积公式对于计算既不作锥形尖灭,也不作楔形尖灭块段的体积适用性较强。以山西省西里北铁矿为例,在分析矿床地质特征的基础上,利用斜楔形体积公式对该矿进行了资源储量估算,分析了斜楔形体的几何形态,验证了斜楔形体积公式,对于提高该矿部分矿体块段资源储量估算的合理性、准确性有一定的参考价值。

Estimation of resources and reserve is an important task in mineral geological explora- tion. The skew cuneiform volume formula is suitable for calculating the volume of a block without tapered tip and without cuneiform tip. Taking Xilibei Iron Deposit in Shanxi Province as an example, based on an- alyzing the geological characteristics of the deposit, the skew cuneiform volume formula is used to estimate the resource reserves of the deposit, the geometric shape of skew cuneiform, and the volume formula is ver- ified, so as to provide some reliable reference for improving the rationality and accuracy of the resources reserves estimation of some ore-bodies of the deposit.
