摘要
三维地震勘探在解决诸如小断层、小构造、煤矿采区陷落柱等方面的应用日益广泛。然而,由于地质条件的复杂性以及各种物探方法的特点不同,有时三维地震勘探方法需要与其它物探方法相结合才能更好地发挥其作用。本文通过一个成功的实例,介绍了利用三维地震和磁法勘探相结合,探测煤矿区小断层、古河床,圈定岩浆岩侵入体范围及边界的方法、特点和经验。
D seismic prospecting is more and mo re extensively used in many aspects s uch as small faults ,small structure s and collapse column in mining areas of coal mine.However,because of complexity of geo logical conditions and different ch aracteristics of geophysical methods,3D seismic prospecting som etimes needs to combine with other ge ophysical methods to give it full pla y role in prospecting.In the paper,through a successful exam ple,the methods and characteristic s and experiences of surveying small faults and old riverbed in mine area and mapping area and boundary of magmatite intrusion using 3D se ismic combine with magnetic prospec ting are introduced.
