Selection of the elastic wave source in the problem of monitoring the state of a carbonate massif using the seismic method

Studying the state of coal-rock masses during their mechanized mining is an important task to ensure safety and efficiency in the extraction of mineral resources. Seismic probing is one of the non-destructive methods for monitoring the state of a rock mass, which is based on registering elastic waves that arise when technological equipment acts on a rock mass. To effectively use this method for monitoring, it is necessary to choose an optimal source of elastic waves taking into account several conditions, including maximum energy efficiency and technological feasibility. The selection of the source of elastic waves is proposed to be performed based on a set of criteria, the deviation from which serves as a condition for classifying the vibration source as interference. This article describes a method for selecting a source of elastic waves in monitoring the state of coal-rock masses using the seismic method. The article is based on an experiment that generated data on signal spectra, amplitude changes, and source location. Based on selected optimality criteria, a reasonable choice was made for the source of elastic waves for further use in monitoring the rock mass. The proposed method can be used in selecting and evaluating the characteristics of sources of elastic waves in preparatory workings of mines and mines that use mechanized mining techniques.
