基于博弈论组合赋权的断层定量评价模型及应用

Fault quantitative evaluation model and application based on game theory combination weighting

为探究一种科学、有效的断层复杂程度评价方法,通过分析断层基本特征指标,基于分形理论,选取断层分维值、断层密度值、断层交变点个数及断层强度指数4个特征指标,利用博弈论思想构建序关系分析法和熵权法的组合赋权方法,对蒋庄煤矿北十采区断层复杂程度进行了评价。结果如下:断层简单及中等构造区主要位于研究区西部、南部及北部,呈环状分布;较复杂构造区主要位于研究区南部及北部,成条状及块状分布;复杂构造区主要位于研究区中部,部分零散分布于南部及北部;极复杂构造区主要呈大块状分布于研究区中部。

In order to explore a scientific and effective fault complexity evaluation method,through analyzing the basic characteristic indicators of the fault,based on the fractal theory,selecting the fractal dimension value of the fault,the fault density value,the number of fault interchange points and the fault intensity index as the evaluation indicators,we use the idea of game theory to construct a combined weighting method of order relation analysis method and entropy weight method,and evaluate the complexity of faults in the north No.10 mining area of Jiangzhuang Coal Mine.The results are as follows:the simple and medium tectonic areas of the fault are mainly located in the west,south and north of the study area,and are distributed in a ring shape;the lower complex structural areas are mainly located in the south and north of the study area,distributed in strips and blocks;the complex structural areas are mainly located in the middle of the study area,and some are scattered in the south and north;the extremely complex structural areas are mainly distributed in the central part of the study area in large blocks.
