Изобретение относитс к горной промышленностии может быть использовано при разработке крутопадающих рудных месторождений.The invention relates to the mining industry and can be used in the development of steeply dipping ore deposits.
Известен способ разработки крутопадающих рудных тел с подэтажным обрушением , включающий образование отрезной щели у вис чего бока и последующую прослойную отбойку руды на зажатую среду скважинами, буримыми из орта. Отбитую руду самоходными машинами доставл ют к рудоспуску 1There is a method of developing steeply dipping ore bodies with subsurface collapse, including the formation of a cutting gap at the hanging side and subsequent layered ore blasting on the squeezed medium by wells drilled from ort. Repulsed ore by self-propelled machines is delivered to ore passes 1
Недостатком указанного способа двл етс большой удельный объем подготовительно-нарезных работ и высокие потери при разубоживании руды.The disadvantage of this method is that a large specific volume of preparatory-rifled work and high losses occur during the dilution of ore.
Известен способ разработки крутопадающих рудных тел, включающий разделку отрезной щели в средней части камеры , послойную отбойку со взрыводоставкой отбитой руды, отбойку междукамерных целиков и потолочины и выпуск отбитой руды под обрушенными породами до по влени их в выпускной выработке 2.There is a method of developing steeply dipping ore bodies, including cutting a cutting gap in the middle of the chamber, layer-by-layer breaking with explosive delivery of broken ore, breaking between chamber pillars and ceilings and releasing broken ore under collapsed rocks until they appear in exhaust mining 2.
Недостаток известного способа заключаетс в больших потер х руды.The disadvantage of this method is the large losses of ore.
Цель изобретени - снижение потерь руды.The purpose of the invention is to reduce the loss of ore.
Поставленна цель достигаетс тем, что производ т торцовый выпуск раздробленной руды междукамерных целиков и потолочины, размещаемых на днище камеры, послойной отбойкой днища камеры в обе стороны от разрезной щели после выпуска через нее камерных запасов. This goal is achieved by the fact that the frontal production of crushed ore between chamber pillars and ceilings placed on the bottom of the chamber is carried out by layer-by-layer breaking of the bottom of the chamber to both sides of the split gap after releasing chamber stocks through it.
На чертеже представлен вертикальный разрез отрабатываемой части рудного тела.The drawing shows a vertical section of the working part of the ore body.
Этаж разбиваетс на два подэтажа. Над основным доставочным горизонтом 1 оставл етс охранный целик 2. На каждом подэтаже проводитс полевой доставочный штрек 3, служащий дл доставки руды в рудоспуск. С доставочного штрека провод тс доставочные орты 4 до вис чего бока, где сбиваютс с вентил ционными восстающими 5; из доставочных ортов провод тс погрузочные заезды 6. Выше доставочного горизонта проходит буровой штрек 7.The floor is divided into two sub-floors. Over the main delivery horizon 1, a protective sill 2 is left. On each sub-floor, a field delivery drift 3 is carried out, which serves to deliver the ore to the ore pass. From the delivery tunnel, delivery ports 4 are carried out to the hanging side, where they are confused with ventilation rebels 5; loading races are carried out from the delivery trucks. A drilling drift passes above the delivery horizon. 7.
Очистные работы начинаютс с разделки щели 8 в середине предполагаемой камеры, после чего производитс выемка камеры 9 с доставкой отбитой руды до щели силой взрваша. Перед каждым взрывом руда из щели убираетс The cleaning work begins with cutting the gap 8 in the middle of the intended chamber, after which chamber 9 is dredged with delivery of broken ore to the gap by explosive force. Before each explosion, the ore is removed from the gap
полностью с. помощью погрузочно7,. вочной машины.completely with. using loading7 ,. perpetual machine.
После выемки камеры до возможных размеров обрушаетс междукамерный целик 10 и потолочина 11. Выпуск руды из щели продолжаетс до по влени в ней породы. Затем сло ми обрушает;СЯ днище 12 камеры 9 и в отступающем пор дке по направлению к доставочному орту продолжаетс выпуск отбитой руды.After the chamber has been removed, the inter-chamber pillar 10 and the ceiling 11 collapse to the possible extent. The ore is released from the gap until the rock appears in it. Then it collapses in layers; the bottom of chamber 12, chamber 9, and in a retreating order towards the delivery unit, the production of broken ore continues.
Использование предлагаемого способа позвол ет снизить потери при снижении разубоживани и объем подготовительно-нарезных работ по сравнению с известными способами.The use of the proposed method allows to reduce losses while reducing dilution and the amount of preparatory-rifled work in comparison with known methods.
