摘要
为了解决某金矿矿体赋存环境和围岩软弱破碎等不利条件使矿石开采难度增大、成本增加等问题,首先利用3DMine程序构建金矿三维工程地质模型;然后,基于距离幂次反比理论,结合金矿西区29副地质勘探线剖面信息,对西区1#、2#、3#、4#、4A#、5#、6#、北矿脉、中间矿脉共9条矿脉进行了金属储量核算和富集分区;最后,根据实际操作能力,按品位值范围将矿体划分为4个富集分区(欠富集区、富集区、较富集区和极富集区);根据实际开采年限,按照品位t=7 g/t划分为2个富集分区(富集区和不富集区)。该研究可为后期矿山开发建设,布置相关开采巷道、溜井、运输平硐、通风井等设施提供决策依据。
The adverse conditions,such as occurrence ol the targeted gold orebody,weak and fractured surrounding rock,have not only brought difficulty in the mining underground,but also increased the operation cost.In view ol that,3DMine software was firstly adopted to build a three-dimensional engineering geological model for the gold mine.Then,based on the theory ol Distance Power Inverse Ratio method,metal reserves estimation and enrichment zone division were performed for 9 veins in the western zone of gold mine(including 1#、2#、3#、4#、4A#、5#、6#veins,Northern vein and middle vein),in combination with sectional information about 29 auxiliary geological prospecting lines.Finally,the orebodies were divided into 4 different enrichment zones(low enrichment,enrichment,higher enrichment,extreme enrichment)in terms of the range of ore grade value in the practical operation.And according to the grade value of 7 g/t,the orebodies were divided into two zones(enrichment zone and non-enrichment zone)in terms of practical service life.This study can be of reference for decision-making in arrangement of relevant mining roadway,orepass,haulage adit,air shaft and other infrastructure facilities in the later-stage of mine development.
