矿区活动断裂多重分形特征及与动力现象关系
Multi-fractal feature of active fracture in mining area and its relation to dynamic phenomenon
摘要
Abstract
In order to analyze the distribution feature of active fracture and its relation to dynamic phenomenon in mining,taking the landform of mining area for research background,the multi-fractal theory was used to calculate for Muchengjian coal mine,Daanshan coal mine,Pingdingshan No.12 coal mine and Laohutai coal mine Ⅴ class active fracture on the basis of geo-dynamic division method.The results show that active fracture in the four mining areas keeps scale invariance in the wide range and belongs to multi-fractal distribution in space,the shape of the multi-fractal spectrum is right hook,the generalized fractal dimension is direct proportion to dynamic phenomenon,and the characteristic parameter and generalized fractal dimension have a well evaluation for mining area dynamic environment.Establishing the evaluation criterion and method of geo-dynamic environment on the basis of generalized fractal dimension and characteristic parameters,and realizing dynamic evaluation of the four coal mine above.This will provide a macroscopic guidance for understanding the active fracture inner feature and the dynamic feature in mining.关键词
