Mine fire is one of the serious disasters in coal mine safety production. Once a fire occurs, it may cause serious personal injury and property damage. In order to effectively prevent and control mine fires, ensure the safety of miners and the normal production and operation of the mine, a series of scientific and reasonable prevention and control measures must be taken.
Fire prevention measures
Mine design and layout: Mine design and layout should fully consider the needs of fire prevention. There should be independent intake and return air systems in the mine to ensure good ventilation and timely discharge of harmful gases and smoke. Multiple emergency exits should be set up at each working face underground to ensure that miners can evacuate quickly in the event of a fire. In addition, there should be fire water sources and fire-fighting equipment underground, such as fire hydrants, fire water tanks, etc.
Fireproof materials and equipment: Fireproof or flame-retardant materials should be selected as much as possible for building materials, equipment, and cables in mines to reduce the risk of fire. Especially for cables, flame-retardant cables for mining should be selected to prevent electrical short circuits from causing fires. The ventilation equipment and mechanical equipment underground should be regularly inspected and maintained to ensure their normal operation and avoid fires caused by equipment failures.
Strict control of fire sources: Open flame operations are strictly prohibited in the mine. Thermal operations such as welding and gas welding must be carried out on the ground. In special circumstances where underground operations are required, strict approval must be obtained and corresponding protective measures must be taken. Miners are strictly prohibited from smoking underground and from carrying matches, lighters, and other sources of ignition into the mine. Clear no fire signs should be set up inside the mine to remind miners to comply with fire prevention regulations.
Strengthening ventilation management: The ventilation system in the mine is an important link in fire prevention, and it is necessary to ensure the normal operation of the ventilation system and timely discharge of harmful gases and smoke. Ventilation equipment should be regularly inspected and maintained, and problems should be promptly addressed. Ventilation monitoring equipment should be installed in various working faces and tunnels within the mine to monitor air quality and harmful gas concentrations in real time, ensuring air circulation and environmental safety.
Fire monitoring and alarm
Fire monitoring system: A fire monitoring system should be installed in the mine, including flame detectors, smoke detectors, temperature sensors, etc., to monitor fire hazards underground in real time. Once a fire signal is detected, the system should automatically sound an alarm and promptly notify relevant personnel to take emergency measures. The fire monitoring system should be regularly inspected and maintained to ensure its sensitivity and reliability.
Communication and alarm system: A comprehensive communication and alarm system should be established in the mine to ensure smooth communication between underground and ground. Once a fire occurs, miners underground should be able to report the situation to the ground in a timely manner through the communication system, and issue an alarm through the alarm system to notify personnel underground and on the ground. The communication and alarm system should be equipped with a backup power supply to ensure normal operation in the event of a power outage.
Fire emergency response
Emergency plan and drill: The mine should develop a detailed fire emergency plan, including fire alarm, evacuation, firefighting and rescue, etc. Emergency plans should be regularly practiced to improve the emergency response capabilities of miners. By simulating a fire scene, miners can become familiar with the emergency operation process after a fire occurs, and master the correct evacuation and self rescue methods.
Escape routes and emergency facilities: Clear escape route signs should be set up at various working faces, tunnels, etc. in the mine, and the routes should be kept unobstructed. Escape routes should lead to multiple safety exits to ensure that miners can evacuate quickly in the event of a fire. Emergency facilities should be equipped underground, such as self rescue devices, emergency lights, escape ropes, etc., for miners to use in emergency situations.
On site fire extinguishing measures: Fire extinguishing equipment should be equipped in the mine, such as fire extinguishers, fire blankets, fire hoses, etc., and they should be ensured to be available at all times. Once a fire occurs, miners should promptly use firefighting equipment for initial firefighting to prevent the spread of the fire. In cases where the fire cannot be controlled, evacuate the scene immediately and wait for professional firefighting teams to carry out firefighting and rescue.
Personnel training and management
Fire prevention knowledge training: Miners should regularly participate in fire prevention knowledge training to understand the hazards and prevention measures of mine fires. The training content should include basic knowledge of mine fires, fire prevention regulations and operating procedures, methods of using fire monitoring and alarm systems, fire emergency plans and evacuation methods, etc. Through training, miners can enhance their awareness of fire prevention and emergency response capabilities.
Safety management system: Mines should establish a sound safety management system, clarifying the fire prevention responsibilities of management personnel and workers at all levels. Regularly inspect and assess the implementation of fire prevention measures, and promptly rectify any problems found. Strengthen the inspection and supervision of key fire prevention areas and links to ensure the effective implementation of fire prevention measures.
Fire drills and assessments: Mines should regularly organize fire drills to simulate fire scenarios and improve the emergency response capabilities and evacuation skills of miners. After the drill, the effectiveness of the drill should be summarized and evaluated, and any problems found should be promptly improved. Through continuous drills and assessments, we ensure that miners can react quickly and respond correctly in the event of a fire.
Mine fire prevention and control is a systematic engineering project that requires taking scientific and reasonable measures from multiple aspects such as design, prevention, monitoring, emergency response, and management. Enterprises should attach great importance to the prevention and control of mine fires, continuously strengthen fire prevention measures and management, and ensure the safety of miners and the normal production and operation of mines. Through full participation, scientific management, and continuous improvement, we can definitely effectively prevent and control mine fires, and ensure coal mine safety production.
