In the complex environment of coal mining, dust suppression is crucial for worker health and safe production. As the core equipment for coal mine dust control, the mist cannon machine requires standardized and scientific operation. The following detailed steps will help coal mines achieve efficient dust suppression.

Step 1: Meticulous Pre-operation Inspection

Before starting the mist cannon machine, a comprehensive inspection is the foundation for safe and stable operation. First, check the equipment's appearance for obvious damage or deformation, and ensure all components are firmly connected to prevent malfunctions caused by loose parts. Next, focus on the water and power systems: confirm the water supply pipeline is intact and unblocked, the water tank level is normal to avoid pump damage from dry running; inspect the power line for integrity, and check terminal blocks for looseness or oxidation. For equipment using a 24V DC safe power supply, ensure voltage stability to adapt to the humid, low-voltage mine environment. Additionally, check whether the nozzles are blocked, the fan blades rotate flexibly, and the intelligent control system's display panel works normally.

Step 2: Orderly Startup Process

After completing the pre-inspection, proceed to start the mist cannon machine. For equipment with local one-key start/stop, simply press the button, and the device will start the water pump, fan, and other components in sequence. For models with remote wireless control, operators can send startup commands from a safe zone away from dust, achieving "human-dust separation" to protect personal safety. During startup, closely observe the equipment's operation, listen for unusual noises or excessive vibration, and check parameter displays (e.g., fan speed, spray pressure) to ensure normal activation.

Step 3: Flexible and Precise Parameter Adjustment

Once started, adjust operating parameters based on actual dust concentration and work scenarios. The 3KW fan frequency converter is key to intelligent regulation, real-time monitoring dust levels to automatically adjust mist volume. However, in special conditions, manually fine-tune spray volume, angle, and fan speed via the control panel. For example, after blasting when dust surges, manually increase mist output and adjust the horizontal rotation angle and air duct elevation to cover a larger area. During low-dust periods, reduce mist volume to save energy. Some advanced models also support remote parameter adjustment via mobile apps or central control systems for added convenience.

Step 4: Attentive Operation Monitoring

Continuous monitoring is essential during operation. Operators should regularly check key indicators like water tank level, power voltage, and equipment temperature to prevent failures from low water, unstable voltage, or overheating. Observe the spray effect to ensure fine, uniform mist without coverage blind spots. If abnormalities occur (e.g., large droplets or uneven spraying), stop the machine immediately to check for blocked nozzles or pump pressure issues. Additionally, pay attention to data from the intelligent dust monitoring system (if equipped), adjusting parameters in real-time based on dust concentration for precise dust suppression.

Step 5: Standardized Shutdown and Maintenance

When completing dust suppression or needing to pause, follow standardized shutdown procedures. First, send a stop command via local buttons or remote control. After the equipment stops, close the water valve and drain the pipeline to prevent freezing in winter or bacterial growth. Then, perform simple cleaning: wipe dust and dirt from the body, clear debris around nozzles. Regularly conduct in-depth maintenance: inspect component wear, replace aging parts, lubricate the fan, and ensure optimal performance. Properly store accessories like remote controls and operation manuals for future use.

Mastering the correct operation of coal mine mist cannon machines not only enhances dust suppression efficiency and ensures workplace safety but also extends equipment lifespan and reduces costs. From pre-start inspection to in-operation monitoring and post-shutdown maintenance, each step embodies the responsibility for safe production and green development. Through scientific operation, let the mist cannon machine maximize its effectiveness in coal mine dust control, building a dual defense line for health and safety in coal mining.
