分形几何学在爆破块度统计中的应用

Application of Fractal Geometry Theory in Blasting Fragmentation Statistics

本文介绍了利用分形几何学的分维数表征岩石爆破破碎块度的统计意义,推导了分维数的求解方法。在实验室条件下采用浇注的混凝土试件代替岩石进行爆破实验,然后应用提出的方法进行了分维数计算。认为分维数是评价岩石爆破块度分布的理想指标,对预期岩石块度的爆破参数设计具有指导作用。

In the paper, the statistical meanings of using fractal geometry to characterize the blasting fragmentation are introduced, and approaches to solving the fractal dimension are deduced. The casting concrete test piece is used to carry out blasting experiment under laboratory conditions, and then calculations are conducted using fore-mentioned approaches. It is considered that the fractal dimension is not only the ideal Indicators to evaluate the distribution of blasting fragmentation, but also has certain directing meanings toward the blasting parameters designs of the expected rock fragmentation.
