THE TECHNIQUE OF HIGH RESOLUTION SEISMIC PROSPECTING IN THE UNDERWORKINGS

Through the analysis of the seismic wave field in the underworkings,the construction and handling methods of the high resolution seismic wave reflected technique is provided.Based on two example of Longkou and Xinji Coal Mine,the feasibility of shallow layer seism technique in the underworkings is verified.The technique is suitable to explore the aquifuge thickness,the lower coal group construction,the interface of Ordovician period,the boundary of upper flooding sandstone,and so on,in the underworkings of the multi-coal beds,inclined coal beds mining area.
