the invention belongs to the field of miner safety, and particularly relates to a safety helmet for a coal mine miner.
Background art:
the gas disaster is always the most main disaster in coal mine safety production, and particularly, the gas explosion disaster has the remarkable characteristics of strong destructiveness, large economic loss, more casualties and the like to cause great threat to the coal mine safety production in China, and the gas disaster is called as a first killer in the coal mine safety production. According to the coal mine accident statistical data of the website of the national safety production supervision and management bureau, the accident starting number and the death number of people above the death person for one time of coal mine production in China are almost the same as the accident starting number and the death number of people above the death person for one time of gas explosion accidents, and the change degree is almost the same, which shows that the gas explosion accidents have the most main influence on the coal mine safety production condition. Due to the complexity of the underground coal mine excavation system, the proportion of high gas mines in China is still high in a long period of time in the future, and the gas explosion hazard risk still generally exists. The gas explosion disaster is still the most important threat in the coal mine safety production process in China and restricts the healthy development of the coal industry in China.
The coal mine gas control work policy of 'pumping first, mining later, monitoring and controlling, and fixed production by wind' is usually adopted for the gas disaster in coal mine safety, but due to the heavy yield and light safety ideas of many enterprises and too low knowledge right of miners for safety, the detected gas can not be regarded as an over standard, and the miners can not make quick action on the gas over standard condition at the first time, so that the coal mine gas disaster continuously appears.
At present, the safety helmet for miners is mainly used for lighting and head safety protection, and can be integrated on the safety helmet by considering that the safety helmet is taken as a necessary protection tool for underground operation, such as real-time monitoring and early warning of gas on a working site, real-time voice talkback, protection glasses, protection earmuffs and the like, and the functions can realize real-time protection and information exchange along with the underground activities of miners.
