摘要
露天矿爆破中爆堆形态的影响因素众多,为找出影响爆堆形态的主控因素,引入灰色关联理论,由于爆堆形态无法用数字参量表达,因此很难直接利用灰色关联理论对其进行计算,通过引入Weibull模型对实测爆堆形态曲线进行拟合计算,完成了爆堆形态参数的量化过程,并对黑岱沟露天煤矿的49组实例进行了灰色关联度计算,得到了各因素对爆堆形态影响的关联序列,并对其进行了分析。该研究对于露天矿爆堆形态的设计优化具有一定的指导意义。
There are many factors influencing the shape of blasted stockpile in the open -pit. In order to find the main influence factors, the grey correlation theory is introduced. However, it is difficult to calculate the shape of blasted stockpile directly using grey correlation theory due to it is unable to express the shape with digital parameters. In this paper, by leading into Weibull model, the fitting calculation of the actual shape curve of blasted stockpile was accomplished, which made quantification of parameters of blasted stockpile. The 49 examples from Heidaigou open -pit were calculated with grey correlation theory, correlativity sequence of influencing factors of the blasted stockpile shape was obtained, and the results were analyzed. The research has definited significance for optimizing the shape design of blasted stockpile in openpit.
