 Abstract. Subject of the research is a methodology for state and properties control of coal rock. Objective of the research is theoretical and experimental substantiation for acoustic-emission massif state control. Elements of acoustic-emission control theory, methodology, means and experiments results of fluid-saturated geomaterials under complex stress state are given. Interpretation of the results of geophysical observations destruction geomaterial theory is based on the provisions of the slip lines . Possible ways to solve the problem of the stress-strain state of fluid-saturated coal seam by setting the autocorrelation coefficients between seismoacoustic events were described. The experimental validation of complex control methods with Fourier disintegration level determination - amplitude-frequency and amplitude-time spectra evaluation were given.

Keywords: rock massif, fluids, destruction, seismoacoustics, spectrum.
