- Abstract
The middle-east region of Qinshui coalfield locates in the eastern of Qinshui block depression, which terrain ups and downs and the surface lithology is changeful. How to choice the excitation and receiving parameters becomes the main difficulty. In this paper, the methods of micro logging and refraction encounter were used to investigate the structures of shallow and surface refined. According to well logging data, determined the reasonable excitation horizon in order to assure the exploration-grains explode in the bedrock or dense clay layer; the excitation parameters of well depth, charge mass and well combination for different lithology are obtained through the study of the systematic test of excitation and receiving condition; through the analysis on the test data, we chose the combination of low frequency detectors and built the recording geometry with multifold. Practices had proved that the excitation and receiving parameters of this region can suppressed the interference waves including the surface wave, multiple refraction wave, etc. and solved the problems of low signal-to-noise ratio in mountainous areas, especially for loess areas, which provides useful references for the exploration and development of unconventional natural gas in the future
