Abstract

Goal. Development of a method for determining the distance to a geophysical phenomenon from one remote measurement point, respectively, using only one three-coordinate seismic probe. The research methodology is based on the methods of mathematical statistics, a systematic analytical approach to the development of the optimal method of determining the distance to a seismic phenomenon based on known theories. Research methods. During the research, methods of mathematical statistics and logic, system-structural and comparative analysis, generalization, systematization and classification were used. Scientific novelty of the obtained results. It consists in the development of an algorithm for conducting research on determining the distance to a seismic phenomenon, using only one three-channel probe. Practical significance: Determination and interpretation of the results of measurements with a three-channel probe, in the future, makes it possible not only to identify the phenomenon, but also to determine the distance to it, which makes it possible to control the redistribution of stresses in the rock massif. The practical significance of the obtained results is that, based on the obtained data, it is possible to characterize the disturbance of the structure of the rock massif and the intensity of the internal destruction of the massif in mine processing located within the limits of the quarry field. Due to the combination of known and new essential features, it became possible to determine the distance to a geomechanical phenomenon from only one available remote measurement point, respectively, using only one three-coordinate seismic probe. This makes it possible to predict the emergence of a void or the exit of a funnel to the surface. Results: the use of the ratio signal duration to the amplitude of the signal makes it possible to compensate for the effect of the phenomenon that the energy dependence of the duration and amplitude on the distance, which in turn allows to ensure the accuracy of the distance determination corresponding to the accuracy of the length and amplitude measurements with a wide range of energy fluctuations of the phenomena. The technical result is the possibility to determine the distances to the hypocenters of seismic events based on the signals of one seismic probe
