Based on the seismic exploration difficulties in data processing, the coal field in mountain area of the reflection wave seismic exploration data processing software and hardware environment were introduced, and the data processing difficulties and countermeasures were analyzed, especially for mountain reflection wave seismic exploration data processing technology and key processing methods were the focus. This processing method was applied in the mountainous area and received good effect, which provided reference for the mountain coal field in the future to the reflection wave seismic exploration data processing research.
