一、通风的重要性在社会主义工业所特有的加强劳动保护的原则下,有色金属矿山作业中,随着采掘的加深、探矿机械化的迅速发展,通风工作的意义也愈益重大了。因为有色金属矿虽不像煤矿坑内危险瓦斯的严重,但也有可能放出有害于人的气体,如岩层中放出的大量的 CO_2、H_2S,坑木及其他物品不断在坑内腐烂所发生的 NO_2和炭酸气,作为机械燃料或照明燃料未完全燃烧所发生的 CO 或燃烧后所发生的 CO_2,以及
I. The Importance of Ventilation Under the principle of strengthening labor protection, which is peculiar to the socialist industry, in the operation of non-ferrous metal mines, with the deepening of extractive mining and the rapid development of prospecting mechanization, the significance of ventilation has become increasingly significant. Because non-ferrous metal mine is not as serious as dangerous gas in coal mine pit, it is also possible to emit harmful gas, such as CO 2, H 2 S released in rock formation, NO 2 and carbonic acid produced by decay of pits and other objects in pit Gas, CO that occurs as incomplete combustion of mechanical fuel or lighting fuel, or CO 2 that occurs after combustion, and
