Abstract
In this paper, a new method based on Hilbert marginal spectrum is presented to solve the problem of coal-rock interface recognition in the top caving process. Coal or waste rock impinges against the tail beam of the hydraulic support. The impact causes the vibration of the tail beam. Because of different intrinsic characteristics, dissimilarities will exist between the two cases. The coal-rock interface is recognized by comparing the Hilbert marginal spectrum. The results show that the proposed method is a promising approach to identifying the coal-rock interface.
