Abstract: The results of research of influence of length of selection of digitized information, widths of spectrum of entrance signal and frequency of sampling frequency, are expounded on the relative error of determination of index of sudden outburst of coal and gas danger determined by a spectral-acoustic method.

Key words: index of danger of sudden outburst of coal and gas spectral-acoustic method relative accuracy the length of the selection frequency of sampling frequency signal spectrum
