摘　　要：为实现煤矿构造复杂程度定量化评价和预测,以口孜东矿13-1煤层为例,在充分利用矿井实际揭露资料基础上,统计了断层分维、断层强度、褶皱分维、煤层倾角变异系数4个构造评价指标,并生成了相应的专题栅格图。结合灰色模糊评价法,应用GIS栅格数据处理功能,计算了各指标权重系数;通过确定隶属函数、聚类分析、隶属度计算,得到了研究区构造复杂程度评价分区图。结果表明:构造复杂区主要位于大、中型构造附近,不利于井网布置、巷道支护与大型设备的使用;构造中等区零星分布于大中型构造旁侧,在煤炭开采过程中需防范次生灾害的发生;构造简单区分布较广,其内断层相对不发育,地层分布稳定,有利于勘探井网的布设和大型机械自动化设备的使用。In order to realize quantitative evaluation and estimation of the complexity of a coal mine structure,we take coal seam 13-1 in the Kouzidong mine as an example,and on the basis of making full use of the information on the actually disclosed part of the mine,make statistics of four structural evaluation indexes,i.e.,fault fractal dimension,fault strength,fold fractal dimension and coefficient of variation of coal seam dip angle,to generate corresponding special grid diagrams.The weight coefficient of each index is calculated by using GIS raster data processing function combined with grey-fuzzy evaluation method.By determining the membership function,clustering analysis and membership calculation,a zoning map of evaluation is obtained for the complexity of the structures in the study area.The results show that the structurally complex areas of the mine are mainly located near large and medium geological structures,which is not conducive to the well pattern arrangement,the roadway support and the use of large equipment.Secondary disasters should be prevented in the coal mining process in the structurally less complex areas,which are scattered beside medium-large geological structures.The structurally simple areas are widely distributed,with relatively undeveloped internal faults,and with stable stratum distribution,which is conducive to the layout of exploration well pattern and the use of large mechanical automation equipment.
