Abstract: High-resolution seismic technology can be widely used in engineering geophysical prospecting. The location and size of gob area can be prospected by using high-resolution seismic prospecting, and the reliable data which evaluates the stability of the ground work of the construction can be provided. This paper also discusses the acquisition, processing and interpretation of data from high-resolution seismic technology in both theory analysis and field experiment, and introduces briefly the practical effect in Jiawang mining district. Experimental results show that high-resolution seismic technique can prospect the mining gob in the ground-work of construction.
