基于灰关联法的影响充填体强度因素的敏感性分析

Sensitivity Analysis of the Factors Affecting Strength of Backfill Based on the Grey Association Method

根据充填材料配比试验结果,采用灰色系统理论中的灰关联分析法,分析了影响充填体强度的各种因素的主次关系,为充填体强度影响因素的敏感性分析提供了一种简捷而有效的方法。结果表明,灰砂比是影响充填体强度的最主要因素,矿山可根据不同充填体强度要求,选择合适的灰砂比,以节省充填成本。

According to the strength test results,the grey correlation analysis method of grey system theory is used to analyze relationship of various factors affecting the strength of backfill,it provides a simple and effective method for sensitivity analysis of factors affecting the strength of backfill.The results show that the lime-sand ratio is the primary factor affecting the strength of backfill.According to different strength requirements of backfilling,the mine can select the appropriate lime-sand ratio to save the backfilling cost.
