All traditional automatic explosion suppression devices used underground in coal mines are of the high-pressure driven type, which pose substantial intrinsic safety risks.Improper operation is prone to causing malfunctions that may injure personnel.Three fatal and injury-causing accidents triggered by misoperation have occurred in 2025 alone.The low-pressure driven mechanical explosion suppression device for underground coal mines can effectively eliminate the safety hazards associated with high-pressure drive systems.Integrated with low-powder explosion suppression technology and multiple safety interlock mechanisms, it further enhances the convenience and safety of on-site application, and fills a domestic technological gap.
