Description
При взрывании зар дов ВВ, которые помещены в скважинах, пробуренных параллельно откосу уступа, имеет место значительный развал горной массы.When blasting explosive charges that are placed in wells drilled parallel to the ledge, there is a significant camber of the rock mass.
Огличне предлагаемого сиособа состоит в том, что дл уменьшени дальности отброса взорванной породы от откоса уступа скважины бур т параллельио плоскости экскаваторного забо .The proposed method is that in order to reduce the distance of the blasted rock from the slope of the step of the borehole, a parallel to the plane of the excavator is drilled.
На чертеже представлена схема, иллюстрирующа предлагаемый способ, где 1 - экскаваторный забой, 2 - скважины на уступе, 3- откос устуиа.The drawing shows a diagram illustrating the proposed method, where 1 is an excavator face, 2 are wells on a ledge, 3 is a ustia slope.
Продольна ось 4 каждой скважнны ориентирована в сторону экскаваторного забо .The longitudinal axis 4 of each borehole is oriented toward the excavator bottom.
Предмет изобретени Subject invention
Снособ сокращени развала горной массы на карьерах прн взрывании колонковых зар дов в наклонных скважинах, отличающийс тем, что, с целью уменьшени дальности отброса взорванной иороды от откоса уступа, скважины бур т параллельно плоскости экскаваторного забо .The method of reducing the collapse of the rock mass in the open pits by blasting coring charges in inclined boreholes, characterized in that, in order to reduce the distance of the blown up blasted rock from the slope of the ledge, the borehole is parallel to the plane of the excavator slab.
