| 摘 要： | 我国有多个煤矿发生过氮气缺氧窒息伤亡事故，一般认为是由于瓦斯风化带中的N2涌出所致。但在徐州垞城煤矿，氮气窒息事故不仅在浅部，也在深部采区发生。分析该矿煤系地层后发现，在氮气窒息事故发生的地点，煤层上方均有红层。根据地球化学理论，可以认为该矿煤系地层中氮气的来源于红层的氧化作用，即成煤物质中的氮元素在成煤阶段形成NH3，上升遇到红层时，可被红层中的Fe2O3氧化生成N2，并赋存在岩层之中。岩石中赋存的N2可通过断层裂隙进入采矿空间，从而造成氮气窒息事故。

| Abstract: | In Cacheng coal mines, suffocation accidents caused by nitrogen gas have occurred. According to the theory of geochemistry and geological trait of this coal mime, A the conclusion can be drawn that the nitrogen gas is originated from oxidation of red bed. During coal formation, nitrogen element in coal-forming material is changed to ammonia gas. When ammonia increases, and contacts with red bed, it will be oxidized to nitrogen gas that is reserved in rock bed. Nitrogen gas can emit into the working place through the fracture of rock fault, and may result in suffocation accidents. |
