Abstract
Изобретение относитс к горному делу и предназначено дл рекультивации земель, нарушенных в ходе ведени горных и геологоразведочных работ. Цель - повышение направленности перемещени горных пород отвалов. На уступе отвала 1 пробуривают взрывные скважины 3, в которых на подошве отвала гидроразрывом формируют котловые уширени 4 и зар жают их ВВ. Между откосом и скважинами 3 на подошве отвала 1 и между подошвой и линией наименьшего сопротивлени в процессе отсыпки отвала 1 формируют полости 2. Объем перебура скважины 3 ниже подошвы отвала 1 равен объему соответствующих котловых уширений 4. В ходе взрывного перемещени горных пород основной поток энергии взрыва перераспредел етс в направлении подошвы уступа, а в ходе перераспределени энергии уменьшаетс дальность разлета породы из верхней части уступа отвала 1. Этим обеспечиваетс перемещение основной массы породы в сторону выработанного пространства. 3 з.п. ф-лы, 1 ил.The invention relates to mining and is intended for the reclamation of land disturbed during mining and exploration. The goal is to increase the direction of movement of the rock dumps. Explosive wells 3 are drilled on the blade of the blade 1, in which boiler broadenings 4 are formed at the sole of the blade by hydraulic fracturing and charge them. Between the slope and the wells 3 at the bottom of the blade 1 and between the sole and the line of least resistance in the process of dumping the blade 1, cavities 2 are formed. The volume of the piercing of the borehole 3 below the bottom of the blade 1 is equal to the volume of the corresponding boiler broadens 4. redistributes towards the bottom of the scarp, and during the redistribution of energy, the distance of the rock from the upper part of the blade 1 is reduced. This ensures that the main mass of the rock moves towards from this space. 3 hp f-ly, 1 ill.
