在矿井下采掘作业中,由于矿岩表面氧化、硫化矿物自燃或水解、有机物(坑木)的腐烂地下涌水、爆破作业、柴油设备的使用以及发生瓦斯、煤(矿)尘爆炸、火灾等原因,将产生一氧化碳、二氧化碳、二氧化硫、硫化氢等多种有毒气体,污染矿井环境。不仅给矿工身体健康带来危害,如有不慎还可造成人身中毒事故,威胁矿工的生命安全。因此,认识矿井有毒气体的危害性,了解中毒的原因和各种症状,掌握正确的急救措施,就能尽量避免中毒事故的发生和减少死亡事故。 In underground mining operations, due to the oxidation of ore rock surface, spontaneous combustion or hydrolysis of sulfide minerals, rotten underground water of organic matter (pit), blasting operation, the use of diesel equipment and the occurrence of gas, coal dust explosion, fire and other reasons , Will produce carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide and other toxic gases, pollution of the mine environment. Not only to the miners health hazards, if inadvertently can also cause personal poisoning, threatening the life and safety of miners. Therefore, understanding the dangers of toxic gases in mines, understanding the causes of poisoning and various symptoms, mastering the correct first aid measures, we can try to avoid the occurrence of poisoning and reduce fatal accidents.
