1. The main points of the three-explosion accident In the "Mine Mine Disaster Prevention and Treatment Plan", some specific requirements have been put forward for the prevention and treatment of major mine disasters. However, due to the suddenness of these disaster accidents, the rescue work is often caught off guard, which may delay the warplanes and expand the situation. Therefore, according to the lessons learned from many major disasters process on China's coal mining history, we proposed a universal strain points have the intention of the leaders and relevant departments in the mine when the accident emergencies, can keep a clear head, to quickly grasp the disaster Responsive, orderly and responsible, coordinate and cooperate, take correct response and treatment measures, and carry out rescue and relief work in order to eliminate disasters as soon as possible or to minimize the disaster. The main points of the three-explosion accident are shown in Table 1. 2. Self-rescue and disaster avoidance in the event of a three-explosion accident When a three-explosion accident occurs in the underground, a strong explosion sound and an air shock wave are generated, and a high-temperature flame and a toxic and harmful gas are instantaneously generated. At this time, the people present and nearby must be calm and calm, and must not be panicked. They should actively rescue themselves and rescue each other according to the characteristics of the three explosions. The method of self-rescue and mutual rescue is: when you hear the explosion sound or feel the air and air waves caused by the explosion shock wave, all personnel should quickly fall back in the direction of the explosion shock wave, face down, the head should be as low as possible, then Cover your mouth and nose with a damp towel, cover your face, and minimize the exposed parts of your body to avoid shock wave damage and instant high temperature burns. Where there is a ditch, it will fall better in the ditch. It is best to hold your breath at the moment of the explosion to prevent the inhalation of toxic high-temperature gas from burning the internal organs. At the same time, you should quickly remove the self-rescuer, quickly wear it according to the method of use, and then identify the direction and leave the disaster area as soon as possible along the disaster avoidance route to the fresh air. When two or more people are traveling together, they should take care of each other. In the retreat, it is necessary to go in the direction of the wind flow. If the roadway is seriously damaged and cannot pass, or if the evacuation route is safe, do not blindly move. Choose a safe place to establish a temporary refuge chamber, and wait quietly and patiently for ambulance. And keep signs such as clothes outdoors so that rescuers can find them in time. Evacuate in an orderly manner to a safe place or wellhead, as determined by expedition. Retreating, if the lamp is off, along iron rails, air pressure, or drain line, the winch rope or the like find their way of roadway, the roadway and left corner mark, the ambulance crew to find. Throughout the disaster avoidance process, everyone must strengthen their confidence, organize themselves consciously, follow the team leader or experienced old workers, strictly observe discipline, unite into a fighting group, and make full use of all equipment and equipment on site to save themselves or save each other. To ensure the safety of personnel. If possible, contact the ground as soon as possible to reach the ambulance in time. There have been many successful cases of miners' self-help and mutual rescue after the explosion. For example, a gas explosion occurred in a mine, and the explosion sound and shock wave broke into the nearby development lane. More than a dozen workers in the tunnel construction were panicked, some ran out, and some shouted. At this critical moment, the old squad leader ordered that no one should run around, quickly evacuate to the work surface, and then stop the local ventilator operation to prevent smoke from entering, while opening all the valves of the pressure air duct, releasing air for the workers to breathe, and forming Positive pressure ventilation of the working face to prevent flame from entering. Using the telephone to get in touch with the dispatching room in time, the ambulance team quickly arrived at the disaster avoidance site, and more than a dozen workers reached the timely rescue, safe escape, no casualties. The working principle of continuous coconut shell Carbonization Furnace,which is adopting advanced smoke-free and environment-friendly carbonization process.

Strain and treatment technical countermeasures for three explosion accidents in coal mines
The three-explosion accident refers to three accidents such as mine gas explosion, mine dust explosion and mine gas and dust explosion. Although the three types of accidents involved in the explosion were not the same, the characteristics of the explosion and the hazards caused by the accidents were many the same or similar. Therefore, the strains and treatment principles of the three explosions were basically the same, and the measures taken were also Greatly different.
