摘　　要：为分析高温高湿环境下地下铝土矿全尾砂充填体强度及其变化规律,构建包括温度湿度在内的充填体强度影响指标体系,统计充填体强度及其影响指标的实测值,构建充填体强度变化规律分析的知识系统。考虑到充填体强度影响指标数值大小含有偏好信息及复杂环境导致的充填体强度带有偶然性的特点,将适用于偏好信息分析的优势关系粗糙集和适用于偶然性分析的变精度粗糙集联合,构建变精度优势关系粗糙集模型,以此分析充填体强度的变化发展趋势及与影响因素之间关系,最终生成充填体强度的概率性偏好规则,并提取出支持数高的规则作为规律。实例表明:采用变精度优势关系粗糙集分析温湿环境下的全尾砂充填体强度变化规律将其应用于矿山实际生产后,因全尾砂充填体强度而引发的安全事故减少50%以上,经济损失减少了60%以上,分析结果全面可靠。To analyze the strength and variation law of underground bauxite full tailings backfill body under high temperature and high humidity environment,a backfill body strength impact indicator system including temperature and humidity was constructed,the measured values of backfill body strength and its impact indicators were counted.A knowledge system for analyzing the variation law of backfill body strength was constructed.Considering that the value of impact index of backfill body strength contains preference information and the backfill body strength due to complex environment is characterized by contingency,the dominance relationship rough set suitable for preference information analysis and the variable precision rough set suitable for contingency analysis are combined to build a variable precision dominance relationship rough set model,so as to analyze the change and development trend of backfill body strength and its relationship with influencing factors.Finally,probabilistic preference rules for the backfill body strength are generated,and rules with high support numbers are extracted as laws.The example shows that variable precision dominance relationship rough set analysis is used to analyze the strength variation law of full tailings backfill body under temperature and humidity environment,and applying it to actual production in mines,the safety accidents caused by the strength of full tailings backfill body are reduced by more than 50%,and the economic losses are reduced by over 60%,the analysis results are comprehensive and reliable.
