Abstract:In this paper, basic theory of short-time fractal filtering was introduced. On the basis of analyzing the noise characteristics of electromagnetic emission (EME) signal during the fracture of coal or rock, short-time fractal fuzzy filtering model of EME signal and determining method of fractal dimension were put forward and applied to EME signal processing of moulding coal and raw coal fracture. The results indicate that it is feasible for short-time fractal filtering method to be used of EME signal processing during the fracture of coal or rock and realizes a self-adapting fuzzy control filtering of EME signal.
Keywords:coal or rock  electromagnetic emission  short-time fractal  filtering
