Isolation of Acousto-Emission Signals at the Background of Noise of Operating mining Machines

For problems of acousto-emission inspection a means has been proposed to isolate signals of pulsed periodic noises produced by operating mining machines. The decisive rule has been proposed on the basis of the developed parameters of a signal form factor and a root-mean-square deviation of the time difference for two neighboring signals. Noise immunity of the method has been examined.

Keywords: acoustic emission, build-up of noise immunity, decisive rule, classification algorithm
