AI Technical Summary
Existing dust control devices in underground mining typically employ a single dust removal method, which is insufficient to effectively control the spread of dust in the mine, resulting in poor dust control performance and failing to meet the needs of safe production and personnel health protection.
A multi-stage dust control device for tunnel face is adopted, which combines foam generating components and atomizing components. Through multi-stage spraying of foam water and water mist, foaming agent is stored in the tank and transported to the foaming machine through the pump to produce foam water. Combined with gas monitoring and booster pump control, multi-stage dust control effect is achieved.
It improved the dust removal effect at the tunnel face, reduced the harm and safety hazards of dust to workers, and enhanced the safety and production efficiency of underground mining.
