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。
In order to find out the main controlling factors that affect the shape of blast furnace, the gray correlation theory is introduced in the opencast mine blasting. Because the shape of the blast can not be expressed by digital parameters, it is very difficult to directly use the gray relational theory , We calculate and calculate the shape curve of blasting reactor by introducing Weibull model to complete the quantitative process of blasting pile shape parameters and calculate the gray relational degree of 49 groups in Heidaigou open-pit coal mine, The impact of blast morphology on the associated sequence, and its analysis. The research is of guiding significance for the design and optimization of blasting stacks in opencast mines.
