The object of research is a mountain massif, processes in it that cause the spread of acoustic vibrations, systems of their registration and processing.
The purpose of the work is to adapt the ARES seismoacoustic control system for forecasting gas-dynamic phenomena in the conditions of the «Management of the mine «POKROVSKE».
Research methods are theoretical and experimental.
Temporal amplitude and spectral characteristics of acoustic emission signals recorded at various stages of rock destruction were studied. The conducted research made it possible to reveal the informativeness of the spectral parameters of acoustic emission signals for the prediction of dynamic rock phenomena. The complex of seismoacoustic equipment should provide for the possibility of studying the spectral characteristics of the signal, their amplitude, total duration and intensity, signal processing, the location of their source, and the generation of a command that warns of the emergence of a dangerous situation.
The scientific significance of the work results lies in the establishment of promising methods of operative industrial safety control, which ensure an increase in the reserve of technological time for decision-making and the implementation of preventive measures to prevent dynamic manifestations of mining pressure.
The work is related to the state budget topics № ІІІ-78-22 "Development of scientific foundations of methods of analysis of wave processes in the mountain environment" and № ІІІ-79-23 "Development of theory and methods of management of potentially dangerous geotechnical systems taking into account risk factors."
The national economic value of the work is determined by the possibility of additional coal extraction and the improvement of miners' work safety. The prospect of further research consists in the development of the standard "Rules of seismo-acoustic forecast of gas-dynamic phenomena during mining operations in coal mines".
