In coal mine production, explosive dust generated during coal crushing and transportation poses a high risk of ignition and explosion. Traditional dust control methods often fail to meet coal mines‘ strict safety requirements due to poor efficiency or hidden hazards.
Mist cannon machines feature explosion-proof designs for core components. Motors and electrical systems use high-strength alloy casings, with tightly sealed wiring and anti-static coatings to prevent sparks and electrostatic discharge—key measures to eliminate explosion triggers.
These machines atomize water into 20–100 micron droplets, effectively adsorbing and settling dust particles. With a spraying range of 30–120 meters and 360° rotational/±45° pitch adjustment, they cover underground and surface areas, reducing dust concentration by over 80%.
Smart systems monitor real-time environmental data (e.g., dust density, humidity) and automatically adjust spraying parameters. When dust levels rise, spraying intensity increases; during environmental changes, modes adapt to optimize water use. Remote operation ensures worker safety and improves efficiency.
A major coal mine deployed mist cannon machines in underground mining faces and surface storage areas. In mining faces, 联动 (interlocked) operation with coal cutters reduced dust from 800mg/m³ to below 120mg/m³. At surface storage sites, they suppressed dust pollution, improving air quality and minimizing environmental penalty risks.
With explosion-proof safety, high efficiency, and intelligent features, mist cannon machines provide a reliable solution for coal mine dust control, protecting production safety and driving the industry’s green transformation.
