Изобретение относитс к горнодобывающей лромышлепности и может быть иапользовано при подземной разработке руд.BACKGROUND OF THE INVENTION The invention relates to mining hromopolescence and can be used in underground mining of ores.
Известен способ подземного обжнга руд в предварительно -подготовленных очистных блоках, лрн котором к перемещающемус по восстанию забою подвод т ,тепловой поток, а обрушенную руду оставл ют в выработанном пространстве.The known method of underground ore-cutting of ores in pre-prepared purification blocks, which are supplied to the bottom of the uprising movement, the heat flow and the collapsed ore are left in the developed space.
Цель изобретени - осуществить предварительный подогрев массива руды в блоке и тем самым повысить эффективность обжнга руды.The purpose of the invention is to preheat the ore mass in the block and thereby increase the efficiency of ore squeezing.
Это достигаетс тем, что отвод газов после обжига .производ т через скважины в блоке.This is achieved in that the removal of gases after calcination is produced through wells in the block.
На чертеже изображен очистной блок, прололънын разрез.The drawing shows a cleaning unit, prololynn cut.
Предварительно подготовленный очистной блок содержит пройденные в верхней частн выработку 1 дл подвода топлива н воздуха Н вентил инОНную выработку 2, соединеииые с нрнзабойным нространством 3 скважинамн 4 и 5. Горелки 6 расположены в выработке / в усть х скважин 4.The preliminarily prepared purification unit contains passed in the upper part production 1 for supplying fuel and air H valve and production 2, connected to the drilling area 3 boreholes 4 and 5. Burners 6 are located in the production / wellhead 4.
Тепловой поток от горелок но скважинам 4 подвод т в нризабойиое пространство 3, гдеThe heat flux from the burners but the wells 4 is fed into the bottomhole space 3, where
происходит обжиг массива в забое с декарбонизацией руды н снижением ее прочности. Обожженна руда постепенно обрущаетс нод действием собственного веса, в результатеAn array is burned in the bottomhole with decarbonization of the ore and a decrease in its strength. The burned ore gradually collapses the node with its own weight, as a result
чего забой перемещаетс ло восстанию.whereby the bottom moves to the uprising.
Пронгедшие через призабойное пространство газы и летучне продукты декарбоанзацин отвод т в вентил цнонную выработку 2 по скважинам 5. При этом руда в массиве подвергаетс предварительиому подогреву, повыша тем самым тепловую эффективность обжига с использованием тепла отход щих газов .The decarboanzacin gases and volatile products, which have penetrated through the bottom hole space, are diverted to the valve production 2 through the wells 5. At the same time, the ore in the massif is preheated, thereby increasing the thermal efficiency of firing using the heat from the exhaust gases.

Снособ подземного обжнга руд в нредварительпо подготовленных очистных блоках,Underground soil cutting method in nredvaritelpo prepared treatment blocks,
при котором к перемеп;ающемус ,по восстанию забою подвод т тепловой поток, а обрушениую руду оставл ют в выработанном пространстве , отличающийс тем, что, с пелью новышени эффектнвностн обжнга, отвод газов носле обжига .производ т через скважины в блоке.in which the heat flux is supplied to the ayuusaus by the bottom of the uprising, the heat of the ore is left in the mined-out, characterized in that, with a new level of effective roasting, the discharge of gases during firing takes place through the wells in the block.
