| Abstract: | This article introduces the inert gas extinguishing device for gas fire in the mine and its working principle, construction and application, investingating the relationship between wind-oil ratio and gas composition, elaborating the great significance and role of the wind-oil ratio automatic control system which can guarantee the gas composition to meet the fire-extinguishing requirements. A comparision of the performance for this kind of extinguishing device with both home and abroad is also available in this article. Experiments have shown that this device can not only extinguish mine fire but also control gas explosion, and is, therefore, an ideal new device to deal with gas fire in mines. |
