HW exploration area is located in the south of Chaoshui basin,its topography shows piedmont alluvial tilt gobi plain and low hills,and the hard and loose sand gravels cause serious impact on the effective detection in coal seismic exploration.How to choose effective gathering parameters is the key to guaranteeing the effectiveness of seismic exploration in the area.Based on seismic exploration experience obtained in adjacent regions,theoretical analysis and experiments,the authors obtained the excitation parameters of well depth,power charge,well combination and well spacing of different areas.Combined with the geological features of the exploration area,the authors selected the combination of multiple linear detectors and built the multifold observation system.The choice of acquisition parameters was carefully constructed and good effect was achieved.The results provide valuable experience and examples for coalfield seismic exploration in similar regions in the future.
