Effect of Wind Speed to Water Mist in Coal Mine Laneway

摘要

There are many factors which affect the effectiveness of the gas explosion suppression by the water mist in the coal mine laneway. This paper studies the relationship between the wind speed and the status of the water mist by numerical analysis. The results shows, for gas explosion suppression in coal mine laneway, the water mist system must be arranged in the region that the wind speed is 5m/s or slower.
