Description

Technical Field

[0001] The invention relates to the technical field of mine fire prevention, and in particular to a reaction temperature monitoring method of a mine fire prevention and extinguishing material. Background Art

[0002] Mine fire prevention and extinguishing materials are an indispensable and important part of coal mine safety production. They act on the fire source in different ways to prevent fire or control the spread of fire. Mine fire prevention and extinguishing materials refer to various substances used to prevent and control mine fires, including grouting materials, inhibitors, foam fire prevention and extinguishing materials, inerting fire prevention and extinguishing materials and colloid fire prevention and extinguishing materials, etc. These materials use specific principles and technical means to destroy at least one of the three necessary conditions for fire (combustibles, combustion-supporting materials, and fire sources), thereby effectively preventing or suppressing the occurrence and development of fire.

[0003] When a fire occurs, fire-fighting materials such as grouting and foam can quickly cover the fire source, isolate oxygen, and reduce the temperature, thereby effectively controlling the spread of the fire. Some materials such as composite colloids and Pratt fire-fighting materials have a long effective period and can continue to play a role after the fire is extinguished to prevent the fire area from re-igniting. By using effective fire-fighting materials, the probability of mine fire accidents can be significantly reduced, thereby reducing the risk of casualties. Fire not only threatens the safety of personnel, but also causes serious damage to mine equipment. The use of fire-fighting materials can protect equipment from fire to a certain extent and extend the service life of equipment. Mine fire-fighting materials play an important role in preventing coal spontaneous combustion, controlling the spread of fire, improving mine safety, and bringing economic benefits. With the advancement of science and technology and the in-depth research, more efficient, environmentally friendly and economical fire-fighting materials will be developed in the future to provide a more solid guarantee for coal mine safety production.

[0004] The existing reaction temperature monitoring method of mine fire extinguishing materials mainly focuses on temperature monitoring, ignoring other important parameters, and cannot fully reflect the effect and safety of fire extinguishing materials. At the same time, the environment inside the mine is complex, and the existing reaction temperature monitoring of mine fire extinguishing materials does not fully consider the actual environment inside the mine, resulting in deviations and inaccuracies in the monitoring results.
