Explosion prevention and protection in underground mines. Protective systems - Passive water trough barriers Ingestion-build-180956 Movement around floors or levelsWater trough barriers are autonomous protective systems by reducing the effects of combustible dust and or firedamp explosions in underground mines to a sufficient level of safety. They are used for preventing the propagation of explosions in roadways in underground coal mines. The purpose of water trough barriers is to extinguish explosion flames in roadways in underground mines and in this way to limit propagation of explosions. Water trough
