METHOD FOR MINING INCLINED ORE BODIES Russian patent published in 1997 - IPC

FIELD: mining industry. SUBSTANCE: according to method, at mining ore reserve in upper half of breast, ore is thrown by blasting force into special trench with flat bottom created in middle of breast and oriented along bearing. After cutting each layer, ore is removed from trench by loading and hauling vehicles with remote control. Trench is created by blasting holes drilled from trench drift with slope being formed at removing ore heap cut in breast without throwing ore into lower ore receiving excavations. Height of slope is assumed with counting of total capacity of trench being sufficient for accommodation of ore mined in layer, taking into consideration its looseness and also with account of flying trajectory of ore lumps cut from upper part of layer so that these lumps fall directly into trench. EFFECT: high efficiency. 2 cl, 4 dwg
