Pitfalls of 3-D seismic explanation and cause analysis

3-D seismic technology,developed in long exploration activities,encountered with many different traps in geologic explanations,such as,same phase wrong breaking caused by false frequency disturbance,false fold caused by error of static corection value,speed pitfal leading to false coal seam shape.In this paper the reasons of these problems are analyzed to solve some questions of 3-D seismic,to raise 3-D seismic achievement's degree of accuracy and credibleness,and to have a better services for coal mining industry.
