瓦斯爆炸作用下井口外部区域灾害分布特征
Distributive Characteristics of Hazards outside Mine Pithead in Gas Explosion
摘要
Abstract
The damaging effects of gas explosions on the area outside the mine pithead incur more accident risks on the auxiliary facilities and related personnel.Combined with typical gas explosion cases and based on computational fluid dynamics technology,this paper studied the gas explosion and its evolution process in coal mines,and investigated the distributive characteristics of the shock wave overpressure and temperature field outside the pithead.The study shows that the main hazard of gas explosion incurs on the area outside the pithead originates from the explosion shock wave along the horizontal direction,and its peak overpressure and spread range increase with the gas quantity while,however,its high temperature hazard on the horizontal direction is not obvious.The conclusions provides an essential referential basis for the site surface layout for coal mining and its related risk assessment and accident investigation.关键词
