基于改进多边形评价法的煤矿安全综合评价研究

Safety Evaluation on Coal Mine based on the Improved Polygon Evaluation Method

应用改进多边形评价法对北宿煤矿安全性进行综合评价。建立了北宿煤矿安全评价指标体系,采用层次分析法确定指标权重,利用问卷与专家打分方式对指标进行量化处理,根据指标多边形面积比确定评价对象安全等级。结果表明,北宿煤矿安全等级为"三级",应用改进多边形评价法对煤矿安全进行综合评价方法简单、直观,评价结果可靠、有效,实用性强。

A comprehensive evaluation was used to estimate the safety of Beisu coal mine based on the improved polygon evaluation method.The safety evaluation index system of Beisu coal mine was established and the analytic hierarchy process was adopted to determine the indexweight. Questionnaires and the method of expert estimation were used to quantify the indicators. According to the area ratio of index polygon,the safety grade of evaluation object was determined. The results showed that, the safety grade of Beisu coal mine was tertiary. This method wassimple and intuitive, and the evaluation results were reliable, effective and practical when it was used to evaluate the safety of coal mine.
