Contract # 211-2014-60050
Start Date 9/1/2014
End Date 8/31/2019
Research Concept

Explosive gas zones in longwall gobs can lead to devastating mine explosions if methane is emitted from the gob into the active mining face area. Research under this capacity-building contract aims to reduce longwall gob related explosions and fires by providing a comprehensive understanding of mine explosion and fire hazards in longwall gobs, along with practical guidance on hazard mitigation strategies.
