RESEARCH OF INFLUENCE OF ACOUSTIC HINDRANCES OF VARIOUS SPECTRAL STRUCTURES ON OUTBURST HAZARD INDICATOR OF THE SPECTRAL AND ACOUSTIC METHOD

The technique of determining the main parameters of digital processing of acoustic signals is described: sampling rates and experimental sample lengths, to provide an error of definition of an indicator of outburst hazard of a spectral and acoustic method of the forecast of outburst hazard in the set limits. An acoustic signal is used as a sounding bottom-hole space of mining «noise» of the executive body of the mining equipment working, to which interference of various amplitudes and spectral composition is imposed.

Keywords: PREDICATION OF THE OUTBURST HAZARD, SPECTRAL–ACOUSTIC METHOD, MEASUREMENT ERROR, DIGITAL SIGNAL PROCESSING, SIGNAL MODELING, SAMPLING FREQUENCY, SAMPLE LENGTH.
