Аннотация

Нами разработан новый алгоритм обработки сейсмологической информации детального шахтного каталога с учетом кинематических и динамических характеристик деформационных волн, распространяющихся с разными скоростями в массиве горных пород, находящегося под интенсивным внешним воздействием в виде массовых или технологических взрывов. В результате чего удалось проследить сценарий подготовки горных ударов с энергией больше, чем 105 Джоуля. Установлено, что волны, распространяющиеся со скоростями от 10 до 1 м/час, являются преимущественным переносчиком энергии в массиве и способствующими ее выделению. События, происходящие в массиве с этими скоростями и обладающие энергией выделения меньше, чем 104 Джоуля, способствуют криповой перестройке массива. События, происходящие в массиве с этими скоростями и обладающие энергией выделения больше, чем 105 Джоуля, могут быть использованы как предвестники, которые рекомендуется принимать во внимание при корректировке произведения взрывов в той или иной части массива. Полное отсутствие этих событий свидетельствует об увеличении напряженного состояния в массиве шахты в целом. Полученная комплексная информация из данных сейсмологического каталога является важной для моделирования и интерпретации распространения сейсмических и деформационных волн в иерархических структурах. Как следует из проведенного анализа, отклики массива для различных градаций расстояний проявляются иногда для всех градаций, иногда только для нескольких. При этом время запаздывания реакции массива на оказанное в виде взрыва воздействие составляет десятки и даже сотни суток. Поэтому высокоэнергетическому отклику предшествует длинный процесс подготовки резонансного выброса энергии, который необходимо сопровождать электромагнитным мониторингом возникновения и скопления дезинтеграционных зон в объеме массива.
