Abstract
The development of faults in Fengfeng mining area was complex.In this paper,the spatial distribution,scale distribution,complexity zoning characteristics and multi-stage evolution process of faults were systematically explored by means of statistical quantitative analysis,fractal dimension quantitative evaluation and tectonic evolution tracing.By constructing a quantitative prediction model of fault drop-extension length,dividing the structural complexity level and zoning,and clarifying the cutting and blocking relationship of different faults,the evolution characteristics of faults in the mining area were revealed,which were'NNE-trending dominant distribution,high-angle concentrated development,and vertical drop increasing with depth',and a technical system of'qualitative characterization-quantitative evaluation' was established.关键词
