Изобретение относитс к горно добывающей промышленности и может быть использовано при проведении восстающих выработок при подготовке рудных блоков к очистным работам.The invention relates to the mining industry and can be used when carrying out rising workings in the preparation of ore blocks for refining operations.
Известны способы проходки восстающих выработок, включающие образование посредством взрывов врубовой полости с после/ 5 ющим взрыванием-/ отбойных скважин 11.Known methods of penetration of the rising workings, including the formation by means of explosions in the heel cavity with after 5 blasting- / firing wells 11.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс способ проходки восстающих выработок, включающий бурение врубовых и отбойных скважин и их взрывание с предварительным образованием врубовой полости 2,The closest in technical essence and the achieved result to the invention is a method of penetrating recurrent workings, including drilling of cutting and drilling wells and their blasting with the preliminary formation of the cutting-in cavity 2,
Однако этот способ имеет р д недостатков . Дл образовани врубовой полости требуетс бурение параллельных врубовых скважин на незначительном рассто нии одна от другой. Отклонени вру- 6oBbtx скважин от вертикали неизбежны. Это обсто тельство приводит к запрес-However, this method has several disadvantages. Drilling parallel well wells at an insignificant distance from one another is required to form the iron ore cavity. Deviations from 6oBbtx wells from the vertical are inevitable. This circumstance leads to

Кроме того, требуетс бурение скважин диаметром более 10О м, дл чего нeoбxoди o специ- альное оборудование.scoop of the mountain mass or to sweep through the firing wells, which entails additional labor costs. In addition, the drilling of wells with a diameter of more than 10 m is required, for which there are special equipment.
Целью изобретени вл етс снижение трудоемкости путем предотвращени запрессовки отбиваемой горной массьиThe aim of the invention is to reduce the labor intensity by preventing the press-in of the rock mass being recovered.
Поставленна цель достигаетс тем, что врубовую полость образуют на гра- Н1ще восстающей выработки и производ т направленное вниз взрывание отбойных скважин, причем направленное взрывание задают веерным бурением отбойных скважин.The goal is achieved by the fact that the cut-in cavity forms on the edge of rising production and produces downward blasting of firing wells, while directional blasting is set by fan drilling of firing wells.
На фиг. 1 изображен продолтзный разрез по восстающей выработке; на фиг. 2 сечерше А-А на фиг. 1.FIG. 1 shows an oblique incision along the rising road; in fig. 2, sect. A-A in FIG. one.
Способ прохопки восстающ выработок осуществл ют следующим образом.The process of digging up workings is carried out as follows.
Врубовые скважины 1 бур т на полную глубину проходки. Р ды отбойных скважин 2-7 бур т под разными угламиCutting holes 1 drill to the full depth of penetration. Rounds of firing wells 2-7 drilled at different angles
