Abstract
Изобретение относитс к подземной разработке рудных тел средней мощности. Цель - снижение потерь руды при отработке целиков. Рудные тела отрабатывают камерами с формированием столбчатых целиков. В процессе выемки руды в почве камер формируют рудный слой, в котором проход т буровые выработки в основани х целиков. Последние разбуривают и взрывают из буровых выработок. При взрывании целиков над буровой выработкой оформл ют потолочину, на которую отбивают запасы целиков в сторону выработанного пространства смежных камер. После обрушени пород кровли на отбитую руду целиков производ т отбойку рудного сло в направлении от обрушенного пространства. Выпуск отбитых запасов рудного сло производ т совместно с отбитыми запасами целиков в торец буровых выработок. 4 ил.This invention relates to the underground mining of medium ore bodies. The goal is to reduce the loss of ore during the mining of the pillars. Ore bodies are worked out with chambers with the formation of columnar pillars. In the process of excavating the ores in the soil of the chambers, an ore layer is formed, in which drilling workings take place in the bases of the pillars. The latter are drilled and blown up from drilling workings. When blasting the pillars above the drill workings, they draw a ceiling, to which the stocks of the pillars are beaten in the direction of the open space of adjacent chambers. After the collapse of the roof rocks on the broken ore, the pillars produce a crushing of the ore layer in the direction from the collapsed space. The production of the broken ore reserves is carried out together with the broken stocks of the pillars at the end of the drilling workings. 4 il.
Description
Изобретение относитс к горному делу и может быть использовано дл разработки- пологопадающих рудных тел преимущественно средней мощности.The invention relates to mining and can be used to develop gently dipping ore bodies of predominantly medium thickness.
Цель изобретени - снижение потерь руды при отработке целиков.The purpose of the invention is to reduce the loss of ore during mining.

Способ осуществл етс следующим образом .The method is carried out as follows.
Вначале ведут выемку руды камерами 1 с оставлением столбчатых целиков 2. При этом в почве камер 1 формируют нетронутый рудный слой 3, в котором проход т буровые выработки 4 в основании целиков 2 с оформлением потолочины 5 над буровой выработкой и смещенной в сторону лежачего бока 6 камер К Из буровых выработок 4 разбуривают целики 2 и рудный слой 3 скважинами 7. В первую очередьInitially, the ore is excavated by chambers 1, leaving columnar pillars 2. At the same time, in the soil of chambers 1, an untouched ore layer 3 is formed, in which drilling workings 4 at the base of pillars 2 are formed with ceiling 5 above the drilling output and shifted towards the lying side 6 To Of the drilling workings 4 drill the pillars 2 and the ore layer 3 wells 7. First
взрывают участки скважин, расположенных в погашаемых целиках 2. При этом целики отбивают на потолочину 5 в сторону выработанного пространства смежных камер . После обрушени пород 8 на отбитую руду 9 производ т отбойку оставленного сло 3 в направлении от обрушенного пространства . Выпуск отбитых запасов рудного сло производ т совместно с отбитыми запасами целиков в торец буровых выработок.explode sections of wells located in the redeemed pillars 2. At the same time, the pillars beat off to the ceiling 5 in the direction of the open space of adjacent chambers. After the rock 8 collapses on the broken ore 9, the left layer 3 is crushed away from the collapsed space. The production of the broken ore reserves is carried out together with the broken stocks of the pillars at the end of the drilling workings.
