基于灰关联分析法的采矿方法优选

Optimal Selection of the Mining Method Based on Grey Relational Method

运用灰色关联分析法对新桥硫铁矿提出的3种采矿方法进行优化选择;将影响采矿方法的因素分为经济指标、安全指标、资源利用率、技术指标4大类;最终得出3种采矿方法的关联度依次为0.865,0.75,0.712,因此选择方法一,即上向水平分层胶结充填法。矿山实践表明,灰色关联理论能够较好地进行采矿方法选择,且得出了比较科学的分析结果。

Grey relational analysis was used in the optimal selection of three mining methods proposed for Xinqiao Py- rite Mine. The factors influencing the mining method were classified into four categories： economic indicators, safety indi- cators, resource utilization rate and technical indicators. The relational degrees of the three mining methods were found to be 0.865, 0.75 and 0. 712 and as a result, the 1st method was selected, which was upward horizontal slicing-cemented filling method. The mine practice shows that grey relational theory can well select the mining method and obtain a more sci- entific analysis result.
