摘要
新构造运动系指晚新生代以来的构造运动,其在天然地震研究、煤田地质与油气勘探、城市建设等领域均具有重要的意义。以淮南顾桥煤矿为研究区,结合区域构造背景和顾桥煤矿的地震地质条件,利用地震解释中的层拉平技术恢复研究区典型剖面的古构造地貌,厘定了各条断层的时空配置关系;结合13块钻孔岩心样品的ESR和热释光年龄,定量分析了断层的发育年代。结果表明:研究区存在新构造运动,且与地震层拉平构造演化预测结论吻合;研究成果对于顾桥煤矿的设计和安全生产的意义。
Neotectonism is indicating tectonism since the Late Cenozoic Era.It has significance in domains of natural earthquake study,coal geological exploration,oil,gas exploration and urban construction.Taking the Guqiao coalmine,Huainan as the subject investigated,combined with regional tectonic setting and seismic-geologic condition in Guqiao coalmine,through horizon flattening technology in seismic data interpretation have restored study area paleostructure and paleogeomorphic features on typical sections,settled faults space-time collocation relationships.Through electron spin resonance(ESR)and thermoluminescent dating for 13 core samples have quantitatively analyzed fault development age.The result has shown that the study area has experienced Neotectonism,and tally with seismic horizon flattening structural evolution predicted results.The study has significance in Guqiao coalmine design and safe production.
