Exemplified by combining the high density resistivity method with seismic refracted wave method to prospect in the same work area and traverses,this paper gives a synthetical contrast and interpretation to divide the stratum interface and determine the thickness of overburden.

Based on refraction p-wave, and the concept of single-emission and double-receiving, forward modeling was used to obtain the acoustic travel time.

Exploration on refraction method of measuring rock loose ring;

Study of low velocity layer via 9-component refraction survey;

T herefore,it needs to carefully analyze and study in many processing steps,well- doing each processing,which includes in repeat tests of key parameters in select ing floating datum and field elevation corrections,detection of refraction,ti me-window of static corrections,non-surface-consistent static corrections,vel ocity analysis and NMO and mute etc.

Application research on geophone re-location technology by refraction wave method;

In this paper, the authors analyze the differences and relations of travel-time curve between refraction wave and reflection wave.
