A Historical Review of Identifying and Mitigating Mine Gas Explosions,r controlling or mitigating gas explosion hazards, which are generally classified as passive and active types. The merits and demerits of each technology are discussed and a comparison among all methods has been done based on their applicability.

Modelling Mine Atmosphere in a Sealed Coal Mine Volume,nt ventilation systems, such as U, W, U?+?L, Y and J types, are simulated respectively. The variation of methane concentration in the gob is analysed and the zone within gas explosion limits concentration is also predicted.

In the U.S., 420 gas explosion disasters were responsible for 10,390 deaths which represented 89.52% of all fatalities in coal mine disaster (As of year 2006). Due to complicated s

The two most important influence factors, the air quantity delivered into the ventilation system and the gas release rate (GRR) in gob namely, are chosen to investigate their impact on the gas explosion region
