摘要
为分析矿区活动断裂分布特征及与动力现象之间的关系,以矿区地貌形态为研究背景,基于地质动力区划活动断裂划分方法,运用多重分形理论对木城涧矿、大安山矿、平顶山十二矿和老虎台矿Ⅴ级活动断裂划分结果进行多重分形计算.研究结果表明:4个矿区断裂体系在较大尺度上都满足标度不变性,空间分布属于多重分形分布,其多重分形谱呈右钩状,广义分形维数D_q与矿山动力现象正相关,特征参数Δf(α)与广义分形维数D_q综合起来能够宏观评估矿区动力环境.建立基于广义分形维数与特征参数的矿区动力环境等级判定准则与评估方法,并实现对以上4个矿区的动力等级评估,为矿山资源开采提前了解区域断裂内在特征及矿区动力环境特征提供宏观指导方向.
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-ffactal spectrtnn is fight hook, the generalized fractal dimension is direct proportion to dynamic phenomenon, and the characteristic parameter and generalized ffactal 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.
