【 摘 要 】

In order to detect accurate watery goaf distribution and impact area in coal mine, and on the base of Transient Electromagnetic detection for Gushuyuan Coal, Simulation of Seismic Processing experimental scheme based on wave field conversion was established. Meanwhile, comparison between traditional transient electromagnetic data processing method and pseudo seismic imaging system was analyzed. The results showed obvious relationship between boundary of watery goaf and 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. Pseudo seismic imaging system can also overcome adverse affection from volume, improve vertical resolution and provide reference for goaf disaster prevention and treatment.
