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。
Three-dimensional seismic exploration has been widely used in solving such problems as small faults, small structures and collapsed columns in coal mining areas. However, due to the complexity of geological conditions and the different characteristics of various geophysical prospecting methods, sometimes 3D seismic prospecting methods need to be combined with other geophysical prospecting methods in order to play their role better. In this paper, a successful example is given to introduce the methods, characteristics and experiences of using three-dimensional seismic and magnetic prospecting to detect small faults and paleo-river beds in the coal mine area and delineate the intrusive body and boundary of magmatic rocks.
