The induced seismicity predicting based on changes in the specific energy of elastic strain of tremor-prone rock layers

The paper presents the method of predicting changes of seismic hazards in the runways of the designed excavation workings. The presented method uses correlations between the level of observed induced seismicity and the estimated energy states of the rockmass. It is possible to make predictions of time-space changes in the number and energy expenditure of the tremors accompanying the planned mining workings and the changes in induced seismicity as a function of time. The presented results of the calculations performed for the selected area of the hard coal mine revealed the existence of a correlation between the energy changes, taking place in the rockmass and the observed level of seismicity. These dependencies can be used to predict seismic hazards of the planned works in the same part of deposits.
