Abstract
Способ образования врубовой полости в породах, склонных к пластической деформации, включающий бурение компенсационной скважины и комплекта врубовых шпуров, часть которых расположена параллельно и часть под углом к оси скважины, заряжание их, взрывание параллельных шпуров в первую очередь, а затем шпуров, расположенных под углом к оси скважины, отличающийся тем, что, с целью повышения эффективности образования врубовой полости за счет лучшей проработки и очистки от раздробленной породы при взрыве параллельных шпуров и использовании эффекта запрессовки устьев отрывающих наклонных шпуров, устья параллельных и наклонных врубовых шпуров, а также забои наклонных и компенсационного шпуров расположены в параллельных плоскостях, отстоящих одна от другой на расстоянии линии наименьшего сопротивления параллельных шпуров, при этом наклонные шпуры заряжаются от забоя до участка пересечения ими границы зоны пластической деформации, образующейся после взрыва параллельных врубовых шпуров.The method of formation of the iron ore cavity in rocks prone to plastic deformation, including the drilling of a compensation well and a set of iron holes, some of which are parallel and part at an angle to the axis of the well, loading them, blasting parallel holes, and then bore holes located at an angle to the axis of the well, characterized in that, in order to increase the efficiency of the formation of the heel cavity due to better development and cleaning of the crushed rock in the explosion of parallel holes and the use of eff To press the mouths of the tearing inclined holes, the mouths of parallel and inclined cutting holes, as well as the faces of inclined and compensation holes are located in parallel planes spaced apart from each other at a distance of the line of least resistance of parallel holes, while inclined holes are charged from the bottom to the site of their crossing zones of plastic deformation formed after the explosion of parallel cutting holes.
