ABSTRACT
Seismic-acoustic method to evaluate type and parameters of faults in mined coal seams was developed in the Institute UkrSRSI, NAS Ukraine. The method is based on the usage of computer-aided systems that allow computing and analyzing parameters of seismic wave fields. Developed criteria to identify faultings with using seismic-acoustic method, which are based on the analysis of signal structure, changes in wave train velocity, frequency and amplitude responses and take into account epigenesis stages and structure of coal-bearing strata allow to reveal anomalies with reliability of up to 80 %.
