APPLICATION OF COMBINATION OF 3D AND 2D SEISMIC EXPLORATION IN COAL FIELD——Taking Yaojie Coal Mine as an Example

Being an important coal production base of Gansu Province,Yaojie coal mine,is coming to exhaustion due to the long time exploitation.In order to obtain the further coal resources,the exploration of coal in depth is extremely urgent.This paper introduced the geological and geophysical features of coal mine area,and the construction design which employ the combination of 3D and 2D seismic exploration to counter the complicated seismic geological conditions.The results of construction proved this method is an effective way to recognize the structures.
