Method of Coal-Rock Boundary Recognition Based on Modal Analysis

Abstract:

Coal rock boundary recognition is one of the core techniques to realize the automation of the fully mechanized coal face, however, this kind of technique has not been effectively resolved. We put forward a kind of coal-rock boundary recognition method based on the modal analysis, and through the theory analysis, we put forward the key parameters and recognition method for the coal rock boundary recognition. By using this method weve analyzed the vibration data from underground working face. The analyzing result indicates that this method could efficiently recognize the coal-rock boundary, which has provided a new and easily realizable method for coal-rock boundary recognition problem.
