中文摘要：

为了对矿山企业综合效益进行评价,构建了矿山企业综合效益评价的多级指标体系。对各指标因素采用更贴合实际情况的区间灰数来描述,并利用极差变换公式对区间灰数指标进行标准化处理,利用灰色区间关联聚类理论,对矿山企业综合效益进行聚类分析,得到了评价结果;并利用灰色粗糙集理论对综合效益评价与指标因素之间的关系进行了粗糙近似决策分析。实例表明：灰色区间关联聚类模型能够对矿山企业综合效益进行评价,可为矿山企业高效生产提供指导与借鉴。

英文摘要：

Multi-level indicators system of comprehensive benefits evaluation to mining enterprises was built to evaluate the comprehensive benefits of mining enterprises.Gray interval number was applied to describe each index in compliance with actual situations,grey range transform formula was adopted to standardize gray interval number indicators and gray interval associated cluster theory was introduced to make clustering analysis of comprehensive benefits of mining enterprises to produce the evaluation result of comprehensive benefits to mining enterprises.Gray Rough Set theory was taken to make rough approximation decision for analyzing the relationship between comprehensive benefits evaluation and its indicators.Practical examples show that the gray interval relational clustering model is able to evaluate the comprehensive benefits of mining enterprises,providing aguidance and reference for the efficient production of mining enterprises.
