THE IMPROVEMENT OF AUTOMATED DYNAMIC PHENOMENA FORECAST METHODS DURING ROOF WEAKENING AND PREVENTIVE HYDROTREATING

The spectral-acoustic method is useful for the automation of the dynamic phenomena forecast and the working area stress control during roof weakening. The acoustic emission method is suggested using for the computer-controlled monitoring of various methods for coal seams preventive hydrotreating and the directional hydraulic fracturing process. The functional relation between charging characteristics and acoustic emission is given.

Key words: COAL SEAM, HARD ROOF, DYNAMIC PHENOMENA, HYDROTREATING, ACOUSTIC EMISSION, SPECTRUM ANALYSIS (ESTIMATION) OF ACOUSTIC SIGNALS
