Изобретение относитс к горной промышленности и предназначено дл повышени безопасности проветривани очистных выработок газовых угольных шахт.The invention relates to the mining industry and is intended to increase the safety of aeration of the clearing workings of gas coal mines.
Известен способ вентил ции очистной выработки, предусматриваюишй подачу части свежего воздуха непосредственно в район сопр жени лавы с вентил иионной i выработкой.There is a known method for ventilating a cleaning mine, providing for the supply of a portion of fresh air directly to the area of the interface between lava and ventilation i production.
Недостатком указанного способа вентил ции вл етс невозможность осуществлени газовой защиты очистной выработки .The disadvantage of this method of ventilation is the impossibility of the gas protection of the treatment output.
Известен также способ автоматическо газовой защиты очистной выработки, проветриваемой сквозной струей с подсве- жением исход щей струи, включающий отключение электропитани при нарушекии газового режима, контролируемого датчиком , расположенным на исход щей -струе аа зовой попсвежени .There is also known a method for automatic gas protection of a treatment generation, aired by a through jet with a flushing of the outgoing jet, including power cuts when the gas mode is disturbed and monitored by a sensor located on the outgoing spraying jet.
Цель изобретени - повьш1ение безопасности проветривани очистной выработки .The purpose of the invention is to increase the safety of the ventilation of the clearing generation.
Указанна цель достигаетс тем, что по предлагаемому способу регулирование концентрации газа в выработке с исход щей струей производ т путем изменени сопротивлени движению подсвежакнией струи при посто нном сопротивлении движению сквозной струи.This goal is achieved by the fact that according to the proposed method, the gas concentration in the production with the outgoing jet is controlled by changing the resistance to movement by the spray jet while the resistance to the movement of the through jet is constant.
На фиг. 1 показана схема осушествле- ни предлагаемого способа в очистном забое; на фиг. 2 - схема осуществлени предлагаемого способа в районе сопр жени лавы с вентил ционным штреком.FIG. 1 shows the scheme of the proposed method in a downhole; in fig. 2 is a schematic diagram of the implementation of the proposed method in the area of lava interface with a ventilation drift.
При установившемс режиме проветривани регулируемое вентил ционное окно 1 имеет определенное проходное сечение и и пропускает необходимое количество воздуха 2, который, смешива сь с- отработанным потоком 3, движетс в отвод щей выработке (выработке с исход щей струей) в общем потоке 4, где установлен датчик 5 метана.In the steady state ventilation mode, the adjustable vent window 1 has a certain flow area and passes the required amount of air 2, which, mixed with the exhaust flow 3, moves in the discharge outlet (discharge with the outlet stream) in the general flow 4, where it is installed 5 methane sensor.
Отклонение концентрации метана в потоке 4 от заданного значени (1,3%) приводит к приоткрыванию или прикрыванию вентил ционного окна 1 в соответстA deviation of methane concentration in stream 4 from a predetermined value (1.3%) leads to the opening or hiding of the ventilation window 1 in accordance with
