【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。本文以济三煤矿十四采区为例,介绍了利用三维地震和瞬变电磁法勘探相结合,探测采区的断层及煤层顶板上100m内的岩层富水体的方法、特点及经验。更多还原

【Abstract】 3D seismic prospecting is widely used in the prospecting of small faults,small structures and collapse column in mining sites of coal mine.However,since the complexity of geological conditions,in order to getting good results, it needs combining other geophysical methods.Based on the 14 mining sites in Jisan coal mine,the method to detect the faults in mining area and water rich terrane within 100m above the coal seam with 3D seismic and transient electromagnetic prospecting is introduced.更多还原
