Ultrasonic Spray Dust Suppression Technology With New High Efficiency Surfactant APG

Combined new high efficiency surfactant APG with ultrasonic spray dust suppression technology, it could greatly enhanced the effect of dust suppression. After this technology was applied in working face 2101, average coal dust concentration dropped to 85.6 mg/m³, dust suppression efficiency reached 86.7%. This technology could effectively suppress dust concentration, APG was biodegradable and it had no irritation for miner's skin.
