摘　　要：资源量估算是固体矿产勘查中的重要内容,目前对其研究多集中在地质统计学或距离幂次反比法。但是对于工作程度较低的矿区却不适用。本文以某钼矿床两条矿体为例,通过对其的资源量进行估算,探讨平行断面法在资源量估算中的应用。平行断面法适用于主要探矿工程布设在勘查线上的任何产状和形状的矿体,估算参数主要包括品位、厚度、面积、体积、体重等。计算表主要有平均品位计算表、断面平均品位计算表、块段体积计算表、块段平均品位计算和矿体矿石量、金属量计算表等。利用WPS软件可以快速、准确地计算相应参数,文中探讨了SUMPRODUCT和SUM公式联合对加权平均品位的计算和IF公式对矿石级别进行判断。Resource estimation is an important content in solid mineral exploration,and most of the current research is focused on geostatistics or inverse distance weighting method.However,it is not suitable for low-grade mining areas.This paper takes two ore bodies in a molybdenum deposit as an example and explores the application of parallel section method in resource estimation.The parallel section method is suitable for any strike and shape of ore bodies where the main exploration engineering is set up along the exploration line.The estimation parameters include grade,thickness,area,volume,weight,etc.The calculation tables mainly include average grade calculation table,cross-section average grade calculation table,block volume calculation table,block average grade calculation and ore volume,metal volume calculation table,etc.The WPS software can quickly and accurately calculate the corresponding parameters.The paper explores the calculation of weighted average grade using the SUM and SUMPRODUCT formulas,and the use of the IF formula to determine the ore grade.
