摘　　要：本文采用SPSS软件对木利锑矿石小体重值与矿石品位、矿石类型开展多元线性回归分析,结果表明,小体重值与矿石类型为低度相关关系,与矿石品位在统计范围内呈高度正相关,矿石品位与矿石类型无相关关系。建模预测验证以往资源储量估算采用的小体重值是合理可靠的。Multiple linear regression analysis was conducted using SPSS software to investigate the small specific gravity of Muli Sb ores in relation to ore grade and type.Results indicate a low correlation between small specific gravity and ore type,but a significant positive correlation with ore grade within statistical ranges.No correlation was observed between ore grade and ore type.Model validation confirms the reliability of the small specific gravity values used in previous resource reserve estimations.
