基于分形理论的芦岭煤矿8煤层顶板断裂构造复杂程度研究

摘要

Based on the systematic analysis and statistics of the Luling coalmine geological exploration and mining data, using fractal theory carried out No.8 coal roof structure complexity assessment Taking the fractal dimension as the basic eigenvalue, divided the coal roof into faulted structural complex, medium and simple regions. The result has shown that the faults in the mine area east and west structural zones were mainly impacted by succeeding NNE tenso-shear tectonic stress, faults are well developed in the area with higher fractal dimensions, thus the structural complex regions, while in the middle structural zone has better strata continuity, only the compresso-share fault F40 has been developed, with relatively small fractal dimensions, thus the structural simple region.%在对芦岭矿地质勘查和开采资料系统分析和统计的基础之上,应用分形理论对8煤层顶板构造进行了复杂程度评价,并以分维值为基本特征量,将煤层顶板划分为断裂构造复杂区、中等区和简单区.研究结果显示,矿区东部与西部构造区的断层主要受后期NNE向张扭性构造应力作用影响,区内断层发育,其分形维数较高,为断裂构造复杂区；而中部地层连续性较好,仅发育F40断层,断层表现为压剪性,该区分形维数相对较小,为断裂构造简单区.
