摘要
本研究以江西省铅山县长寿源银铅矿区为研究对象,基于高精度钻探勘查数据和矿山生产坑道系统数据,采用垂直纵投影地质块段法对矿区资源储量进行精细化评估。结果表明:矿区Ⅱ-1号主矿体呈脉状、舒缓状展布,走向100°~110°,倾角60°~80°,平均厚度2.24m(变化系数79.04%),属厚度较稳定型矿体;矿石平均品位Ag123.05g/t(变化系数76.65%)、Pb 1.51%(变化系数118.63%),有用组分分布均匀-较均匀。矿区保有(122b+333类)资源储量矿石量366.68千吨,Ag金属量45.12吨,Pb金属量5539吨;累计探明资源储量773.29千吨,Ag金属量96.19吨。结合矿床开采技术条件,在当前市场环境下,长寿源矿区矿山有一定的开发价值,研究结果为矿山后续开发提供了科学依据。
This study focuses on the Changshouyuan silver-lead mining area in Yanshan County,Jiangxi Province.Based on high-precision drilling exploration data and data from the mine's production tunnel system,the vertical longitudinal projection geological block method was employed to evaluate the resource reserves in the mining area.The results indicate that the main ore body(Ⅱ-1)in the mining area exhibits a vein-like and gently undulating distribution,with a strike direction of 100°~110°and a dip angle of 60°~80°.The average thickness is 2.24m(with a coefficient of variation of 79.04%),classifying it as a relatively stable-thickness ore body.The average ore grades are 123.05g/t for Ag(with a coefficient of variation of 76.65%)and 1.51% for Pb(with a coefficient of variation of 118.63%),indicating a uniform to relatively uniform distribution of valuable components.The remaining(122b+333 category)resource reserves in the mining area amount to 366.68 kilotons of ore,with 45.12 tons of Ag metal and 5,539 tons of Pb metal.The cumulative proven resource reserves total 773.29 kilotons of ore,containing 96.19 tons of Ag metal.Considering the technical conditions for ore deposit exploitation and the current market environment,the Changshouyuan mining area has certain development value.The research findings provide a scientific basis for the subsequent development of the mine.
