摘要
断层构造定量评价的重要指标之一是断裂分维值,这一指标可以有效并准确地描述断层构造的复杂程度。为了解决以往统计计算方法复杂繁琐、工作量大等问题,基于MAPGIS平台,利用其处理分析功能提取断层数据,并借助MAPGIS辅助软件SECTION进行网格单元划分,优化了快速计算矿井断层断裂分维值的定量评价方法。依据分形理论与断裂分维值定义的计算公式,用山西新元煤矿的实例验证了方法的可行性,得到分维值为1.1595,且相关系数在0.97以上。结果表明,利用MAPGIS计算断裂分维值方法简便,可操作性强。
One of the important indexes for quantitative evaluation of fault structure is the fracturefractal dimension,which can effectively and accurately describe the complexity of fault structure.In order to solve the problems of complicated and heavy workload of previous statistical calculation methods,based on MAPGIS platform,the fault data was extracted by using its processing and analysis function,and the grid unit was divided by using MAPGIS auxiliary software section,the quantitative evaluation method of fast calculating fractal dimension value of mine fault was optimized.According to the fractal theory and the definition formula,the fracture fractal dimension values were calculated,the feasibility was verified in a mine of Shanxi Province,the fractal dimension was 1.1595,and the correlation coefficient was above 0.97.The results showed that the method of calculating fracture fractal dimension by MAPGIS was simple and operable.
