摘要
根据分形几何理论得出爆堆块度分布和块度分维数的关联关系,然后根据现场爆堆块度分布建立爆堆块度分维值与爆破参数的关系,从而达到指导人们进行爆破参数优化,控制煤体爆破块度,进行爆前的块度估算和块度预测的目的.
According to theory of fractal geometry, the relations of fragmentation distribution of blasting lumps and the fractals of fragmentation was got, and then established the relation of coal blasting lumps fragmentation of fractal value and parameters of blasting according to field, as well as guides the optimization of blasting parameters, and controls fragmentation of coal blasting, in order to estimate and forecast fragmentation before blasting.
