Abstract

Изобретение относитс  к горной промышленности и может быть использовано дл  регулировани  распределени  расхода воздуха в вентил ционных сет х. Цель изобретени -повышение расхода воздуха в горной выработке. Эжектирующа  установка имеет основной 1 и дополнительный 2 вентил торы. Дополнительный вентил тор 2 установлен в одном поперечном сечении с основным вентил тором 1. Оба вентил тора 1 и 2 размещены у противоположных боковых стенок 3 горной выработки 4 на высоте, равной половине высоты горной выработки . Така  установка вентил торов 1 и 2 при работе эжектирующей установки приводит к увеличению безразмерного запаса кинетической струи вентил торов, увеличению эжекти- руемого воздуха и повышению расхода воздуха в горной выработке 4,2 ил.The invention relates to the mining industry and can be used to control the distribution of air flow in ventilation networks. The purpose of the invention is to increase air consumption in mine workings. The ejecting unit has a main 1 and an additional 2 fans. An additional fan 2 is installed in the same cross section with the main fan 1. Both fans 1 and 2 are placed against opposite side walls 3 of the mine workings 4 at a height equal to half the height of the mine workings. Such an installation of fans 1 and 2 during the operation of an ejecting installation leads to an increase in the dimensionless reserve of the kinetic jet of fans, an increase in the ejected air and an increase in the air consumption in the mine workings of 4.2 silt.
