Исследован процесс разрушения горных пород Хибинского месторождения в камере всестороннего давления с регистрацией событий акустической эмиссии. Рассчитаны координаты гипоцентров событий акустической эмиссии в процессе эксперимента, проанализирован процесс формирования образа катастрофического макроразрушения и определены сопутствующие напряжения. Установлено, что доминирующей геометрией хрупкого разрушения горных пород является диагональный макроразрыв. Определено, что процесс разрушения происходит не мгновенно, а с развитием очага разрушения во времени. Результаты исследований имеют важное практическое значение для своевременного обнаружения критической стадии развития очага разрушения.
