Global warming and the subsequent climate change have become worldwide environmental and anthropogenic concerns. Methane and CO2 are the most potent of the greenhouse gases (GHGs), and one of the most promising methods of methane abatement is for methane to be captured through thermal decomposition processes. However, this approach introduces a major safety concern related to methane explosions and flame propagation in coal mines. It is vital that all of the safety issues related to this approach are addressed prior to the implementation of GHG emission control. This study investigates the effectiveness of venting in the event of methane explosions. In addition, the study examines the scaling effects by integrating the experimental results from this study with the data from previous explosion experiments carried out in a smaller scale experimental apparatus. The experimental setup consisted of a 1 m3 explosion chamber connected to a 9.7 m long venting duct. The results indicated that the methane explosion...
