【摘要】 断裂构造的定量预测一直是地质工作中的一个难点。断裂构造影响了矿井的安全生产和煤矿开采效率。本文在前人研究构造预测的基础上,详细搜集新汶煤田构造资料,深入分析和归纳煤田构造基本特征,提出利用分形理论的相关研究方法,解决断裂构造定量预测这一难题,并且针对实际工作中存在的问题,提出了具体的解决方案和处理手段。首先分析了新汶煤田地质概况,研究了相关区域地质构造背景,对新汶煤田已揭露各种断裂构造形迹及其它信息进行统计、整理,根据断裂构造特征,将新汶煤田划分为十个分区,绘制各分区及全区的小构造走向玫瑰花图,分析新汶煤田断裂构造基本规律。利用断裂构造所表现出的各种基本特征和相互关系,结合分形几何理论在地质领域的应用,作出小断层落差和频度的散点图,利用断层中应用最多的相似维(Ds),计算出断层长度和落差的分维值(Ds),得到区域内关于断层长度和落差预测的相关经验公式。根据预测断层长度和落差的相关公式,结合已知相关资料和参数,从而能够预测区域内某一未开采块段的断层条数、断层长度及落差。断裂构造的分形分析,不仅能定量地对构造复杂程度进行评价,而且能进行定量预测。根据掌握的信息和资料运用合适的科学方法对断裂构造提出一定精度的评价和预测,这对保证采掘工作的正常顺利进行,对指导矿井的安全生产,提高煤矿开采效率,保证国家资源的充分开发与合理利用,具有重要的实际作用与意义。更多还原

【Abstract】 Quantitative prediction of faults in the geological work has been a hard nut to crack. Faults affect the safety of the mine production and the efficiency of coal mining. The paper based on structure prediction of previous studies, collected detailed information of Xinwen coalfield faults, analyzed in-depth and summarized the law of coalfield structure, made use of fractal theory related to research methods to solve the problems of the quantitative prediction of faults. According to the existing problems of practical work, proposed specific solutions and the means to deal with.First, the author analyzed Xinwen coalfield geology, studied the relevant background of the regional geological structure, had a statistics and analysis of information of Xinwen coalfield faults exposed and other information. And in accordance with the characteristics of faults, divided Xinwen coalfield into 10 regions, drew trend rose diagram of small structure of divisional and integral region, analyzed the basic law of coalfield faults of Xinwen coalfield. Using fault structure which shown by the various laws and the relationship between the combination of fractal geometry theory in the field of geological applications, to get small faults and frequency difference of the scatter. By using the application of the most similar to Victoria (DS), the author calculate the difference of fault length and fractal dimension (DS) and the relevant empirical formula prediction of the fault length and drop in region. According the fault length and the related formula, combining with known information and parameters, a non-mining region of the fault block, fault length and gap can be predicted. The method about fractal fault analysis, is not only for quantitative evaluation of the complexity of the structure, but also for quantitative prediction. According to the information and data, the author used appropriate scientific methods to evaluate and predict the fault structure, which can ensure that the extraction of the smooth conduct of the normal work of guiding the mine production safety and improve the efficiency of coal mining and ensure that national resources full developed and play an important role on rational utilization.更多还原
