Test on blasting parameter optimization of coal blasting mining face in thin seam with partings
含煤矸石薄煤层炮采面爆破参数的优化试验
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
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，拉制煤体爆破块度，进行爆前的块度估算和块度预测的目的。
