Abstract：On the basis of field seismic experiments conducted in Dongpu Depression, a scheme is presented of choosing optimum shot depth and perfect receiving system which are suited to this particular area. 1. The filtering character of ghost in surface layer must be taken into consideration in choosing optimum shot depth. Field experiments in this region show that the frequency band of seismic wave narrows with the increase in shot depth, and that as shot depth increases, low frequency waves are enhanced while high frequency contents weakened. Thexefore, the optimum shot depth is 11-20 meters. 2. The filtering charactcrs of earth and receiving system must be considered in the course of designing optimum receiving system. Experiments lead to the conclusion that SJ-1 geophone is good for 18 meter shot depth and GSE-201 seismic detector is suitable for the shot depth of 27 meters; and that in the case of shallow hole pattern shooting in the configuration of 4.5m*5, better result can be obtained with SJ-1 geophone.
