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 characteristics of active faults in the mining area and its relationship with the dynamic phenomena, taking the geomorphology of the mining area as the research background, based on the method of dividing the active faults by the geodynamic dynamic zoning and applying the multifractal theory to the 12th mine of the Muchengjian Mine, Da’an Mine, And the results of multi-fractal analysis of the Ⅴ-level active faults of the Tiger Station. The results show that the fracture systems of the four mining areas satisfy the scale invariance on a large scale and the spatial distribution belongs to the multifractal distribution. The multifractal spectrum has a right hook The generalized fractal dimension D_q is positively correlated with the mine dynamic phenomenon, and the characteristic parameter Δf (α) and the generalized fractal dimension D_q can be combined to evaluate the dynamic environment of the mine area.Considering the generalized fractal dimension and the characteristic parameters, Criteria and assessment methods, and to achieve the dynamic rating of the above four mining areas, providing macro guidance for understanding the inherent characteristics of regional faults and the dynamic environment of mining resources in advance.
