“…We should mention that for the depth-wise distances, the scatters of the parameter s and standard error V for different magnitudes are higher than for the epicentral distances. This is connected with the higher errors in the determination of depths than epicenters, and, probably with the depth-wise nonuniformity of the stress fields, which increase probability of dynamic events triggered due to rock pressure [22,23], which may lead to variations in the depth-wise decrease in the number of triggered events characterized by the parameter s. In any case, for the epicentral distances (see fig. 1) and depth-wise distances (see fig.…”

“…Разрушение породных целиков в значительной степени определяет устойчивость пород как в кровле, так и в боках горных выработок [11,[15][16][17]. Зоны разрушения пород ограничиваются участками, где напряженное состояние породного массива близко к одноосному сжатию, и по мере удаления от контура породного целика и перехода к объемному напряженному состоянию процессы разрушения пород быстро затухают [18].…”
