摘　　要：为了防止采掘过程中无计划揭露地质构造和地质构造引发的灾害,丰富地质构造探测预报技术,开展了基于构造影响特征的断层构造预测技术研究,提出了利用构造影响特征推断前方断层及影响范围的思想和技术途径。通过对赵庄矿地质构造影响下突出危险指标、煤层厚度、夹矸厚度、瓦斯涌出等变化特征的分析,从中挖掘、提取这些信息特征—构造影响特征,建立了多维构造影响特征指标体系和断层构造综合预测模型,并在赵庄矿进行了成功应用。应用结果表明,通过分析采掘期间各种生产安全信息蕴含的构造影响特征变化情况,采用地质构造综合预测模型,能够实现工作面前方断层构造的超前预测,提高勘探钻孔施工的针对性,降低地质构造勘探的成本。In order to prevent unplanned exposure of geological structures and disasters caused by geological structures during the process of excavation,enrich tectonics detection and prediction technology,research on structural prediction techniques based on structural impact characteristics was carried out.The idea and technical approach of using structural influence features to infer the front fault and its influence range were proposed.By analyzing the characteristics of changes in outburst risk indicators,coal seam thickness,gangue thickness,and gas emission under the influence of geological structure in Zhaozhuang Mine,these information characteristics-structural influence characteristics were mined and extracted.A multi-dimensional structural impact characteristic index system and a comprehensive prediction model for fault structures were established and applied in practice in Zhaozhuang Mine.The research results showed that using various production safety information during the mining period,by analyzing the changes of structural impact characteristics contained in these information,and using the comprehensive prediction model of tectonics,the advance prediction of fault structure in front of the working face can be achieved,improving the pertinence of exploration drilling construction,and reducing the cost of geological structure exploration.
