爆堆块度分布的自动与分形测试系统的应用

Research on automatic and fractal testing system of distribution of pit pile's fragmentation

露天矿爆堆矿岩块度分布是评价爆破效果最重要的指标,但其分布参数非常难以获得。如何准确地的获得爆堆各级岩块的组成是国内外众多采矿界学者研究的重要课题之一。采用摄影测量的方法去获得求算爆堆块度分布分形模型中分维数的基础数据,即解决了摄影测量分析系统的“小块漏失”现象,又为分形测试系统的推广应用奠定了基础。本文重点介绍了自动测试系统和分形测试系统在阜新矿务局海州煤矿的应用与分析。

Distribution of pit pile抯 fragmentation of strip mine is the most important index for assessing the explosion effect, but its parameters of distribution is hard to be got. How to get accurately the composition of pit pile抯 is one of the important problems which is studied by many mining scholars in the world. Using photography measure technology can achieve basic data which is utilized to calculate fractal dimensions in fractal model of distribution of pit pile抯 fragmentation .The measure avails to overcome the phenomenon of 搇ittle piece leaking 攚hen its data is used in analysis system , and besides , it lays a foundation for popularizing and applying fractal measure system .This paper puts its emphasis on application and analysis of automatic testing system and fractal testing system at Haizhou Coal Mine of Fuxin Mining Bureau .
