Description
(54) СПОСОБ РАЗРАБОТКИ РУДНЫХ МЕСТОРОЖДЕНИЙ(54) METHOD FOR DEVELOPING MINERAL DEPOSITS
ный разрез; на фиг. 2 - сечение А-А на фиг. 1.ny incision; in fig. 2 is a section A-A in FIG. one.
Подготовка очистной камеры 1 к отработке заключаетс в проведении двух буровых выработок 2 и 3 по границе камеры с целиком буровой нодсечцой выработки 4 по центру камеры и доставочной выработки 5.The preparation of the cleaning chamber 1 for working out consists in carrying out two drilling workings 2 and 3 along the border of the chamber with the entire drilling subassembly of production 4 in the center of the chamber and delivery production 5.
Буровую подсечную выработку 4 с доставочной выработкой 5 сбивают выпускными нишами 6.Drilled razchechnuyu production 4 with delivery production 5 knock down the exhaust niches 6.
Отбойку полезного ископаемого производ т веерами скважин, буримых из выработок 2, 3 и 4. При этом боковые скважины 7 нижнего веера, направленные к междукамерным целикам 8, недобуривают до контура камеры.Mineral blasting is performed by fans of wells drilled from workings 2, 3, and 4. In this case, the side wells 7 of the lower fan, directed towards the inter-chamber pillars 8, are not filled to the outline of the chamber.
По границе камеры с целиками из выработок 2 и 3 бур т параллельные сближенные скважины 9, причем нисход щие скважины бур т до контура днища. Сближенные скважины зар жают зар дами меньщей . мощности одновременно со скважинами веера, а взрывают вместе с оконтуривающими скважинами 10 веера мгновенно, но с замедлением относительно отбойных скважин 11.Along the border of the chamber with pillars from openings 2 and 3, parallel contiguous wells 9 are drilled, and the downhole wells are drilled to the bottom contour. Approximate wells are charged with smaller charges. power simultaneously with the wells of the fan, and they blow up together with the contouring wells of the 10 fans instantly, but with deceleration relative to the firing wells 11
Расположение сближенных скважин по контуру камеры и одновременное их взрывание при небольщом рассто нии между ними (коэффициент сближени зар дов 1) значительно снижает нарушенность междукамерных целиков вследствие того, что разрущение массива между скважинами происходит настолько быстро, что трещины в направлении целиков практически не распростран ютс . Это позвол ет уменьшить размеры целиков, сохран их устойчивость, и тем самым повысить извлечение полезного ископаемого.The location of contiguous wells along the contour of the chamber and their simultaneous blasting with a small distance between them (charge transfer ratio 1) significantly reduces the disturbance between the chamber pillars due to the fact that the destruction of the array between the wells occurs so quickly that the cracks in the direction of the pillars practically do not spread. This makes it possible to reduce the size of the pillars, preserving their stability, and thereby increase the extraction of minerals.
Предлагаемый способ разработки рудных месторождений возможно применить при отработке как крепких, так и малопрочных пород.The proposed method of developing ore deposits may be used in the development of both hard and low-strength rocks.
