Abstract
Для минимизации нитрозных газов в вентиляционных струях при подземных горных работах и в туннелестроении предложены способ и установка, причем соответствующие содержащие компоненты Noгазообразные продукты взрыва или выбросы дизельных агрегатов улавливаются в месте возникновения, а затем очищаются. При этом очистка происходит так, что значения ПДК соблюдаются так, как они заданы или как будут действительны в будущем. Для этого после собственно удаления пыли предусмотрена целенаправленная очистка No, которая гарантирует, что очищенный таким образом шахтный воздух затем снова может быть введен в обычную вентиляционную струю.To minimize nitrous gases in ventilation jets during underground mining and in tunneling, a method and installation have been proposed, with the corresponding containing components No-gas explosion products or emissions of diesel units being collected at the site of origin and then purified. In this case, the cleaning takes place in such a way that the MPC values are observed as they are set or as they will be valid in the future. To do this, after the actual removal of dust, targeted No-cleaning is provided, which ensures that the mine air purified in this way can then be reintroduced into the usual air flow.
