摘要
根据爆破岩体相关实测数据,利用岩体的灰色性和多指标性,采用灰色关联分析法对该岩体进行可爆性分析,确定岩体可爆性级别,从而选取合适的爆破参数.此种方法通过定量计算来确定岩体爆破性级别,区别于以往的定性分析,可以避免主观因素对权重确定的影响,更客观地体现各个分级指标对可爆性分级的贡献,因此,方法可靠且简单易行.
Grey relational analysis is used to analyze and grade the blastability of a rock - mass in terms of its uncertainties and indeterminaeies, and of the experimental statistics of rock - mass blast. Proper blasting parameters are then selected based on the analysis. Unlike the conventional qualitative analysis, grey relational analysis is a quantitative - calculation - oriented approach, therefore is capable of eliminating any subjective interference with the analysis, and hence will objectively indicate the individual contribution of each grading index to the overall blastability grading of a rockmass.
