ABSTRACT

In order to accurately detect watery goaf distribution and impact area in coal mine and on the basis of transient electromagnetic detection for the Gushuyuan coal mine, simulation of seismic processing experimental scheme based on wave-field conversion was established. Meanwhile, the comparison between traditional transient electromagnetic data processing method and pseudo-seismic imaging system was analyzed. The results showed an obvious relationship between the boundary of watery goaf and the geological electrical interface. Pseudo-seismic imaging system based on wave-field conversion can show more efficiency to distinguish depth and boundary range of watery goaf than traditional transient electromagnetic data processing method. This system can also overcome adverse effects on volume, improve vertical resolution, and provide reference for goaf disaster prevention and treatment.
