摘要
断裂构造的分维值是定量评价矿井断裂构造复杂程度的重要指标,针对其在评价过程中数据统计方法繁杂、精度低等现状,在AutoCAD平台上,依据分形盒维数测定的原理和方法用Au-toLISP语言编写程序实现了断裂分维值的自动化统计功能,并用钱营孜煤矿的实例验证了程序统计的正确性。结果表明:用程序计算的分维值为0.424 5～1.590 7,且各块段相关系数R绝大多数在0.95以上,表明程序统计的正确性和精确性,提高了科研分析工作效率。
The dimension value of the fractural structure would he an important index to quantitatively evaluate the complicated degree of the mine fractural structure. According to the complicated, and low accuracy of the data statistic method in the evaluation process, on the AutoCAD platform, fractal box dimension, based on the principle and method of the fractal box dimension measurement, the AutoLISP language writing program was applied to realize the automatic statistic function of the fractural dimension. A case of Qianyingzi Mine was applied to verify the correction of the program. The results showed that the dimension value calculated with the program was 0. 424 5 1. 590 7 and the related coefficient R of each block section was mostly over 0. 95 which could show the correctness and accuracy of the pro-grammed calculation.
