      <abstract xml:lang="ru">
        <p>Исследования геологических и структурных особенностей строения массива показали, что в андезитах с глубиной наблюдаются сбросы диагонального типа, разрывающие рудную зону на блоки. Ширина сбросов до 1 м, а в некоторых случаях и больше. Наличие сбросов существенным об­разом влияет на процесс бурения и качество взрывоподготовки горной массы. Диагональные сбросы имеют крутое падение, а кливажи и трещины - пологое. Пологое падение трещин ока­зывает сильное влияние на условия распространения взрывных волн, что необходимо учиты­вать при проектировании взрывных работ ...</p>

      <abstract xml:lang="en">
        <p>Studies of geological and structural features of the massif structure have shown that in andesites with depth there are diagonal type faults, which break the ore zone into blocks. The width of the faults is up to 1 m, and in some cases even more. Presence of faults essentially influences the process of drilling and quality of rock blasting. Diagonal faults have a steep drop and jibs and fractures have a gentle drop. The gentle dip of cracks has a strong influence on the conditions of propagation of explosive waves, which must be taken into account in the design of blasting operations.</p>
