THE RESEARCH OF THE METHOD FOR GETTING THE PARAMETERS OF LOW-VELOCITY ZONES BY USING DIRECT WAVE

In coal seismic prospecting,the mejority of shot-hole are under the low-velocity zones. The Parameters of low-velocity zones can be obtained from direct wave and the statics of these parameters can be done. The method of picking up the primary waves, the principle and method of getting the parameters of lowvelocity zones and the effect of statics are introduced.
