Generally if someone passes out,，进入矿区后聚集，就会产生这种结果。
Carbon monoxide - (10ppm generally limit) incomplete combustion (badly running engine, or bush fire starved of sufficient oxygen), tends to accumulate in low points in areas where the air is stagnant. Absorbed by the body faster than oxygen & causes headache.
一氧化碳（通常以10PPM为限度）：不完全的燃烧（性能很差的机器的运行或因缺氧熄灭的森林火灾）所产生的气体，往往会聚集在空气不流通的低凹地带。人体对这种气体的吸入速度超过对氧气，将会引起头疼。
carbon dioxide (generally 2000ppm) headache, absorbed by the body faster than oxygen & causes headaches & shortness of breath.
二氧化碳（通常以2000PPM为限度）人体对这种气体的吸入速度超过对氧气，将会引起头疼，并呼吸急促。
Hydrogen sulphide smells like rotten eggs, found in old tunnels where there may have been stagnant water flammable & explosive, but can be easily detected through smell (initially).
硫化氢闻起来象臭鸡蛋味。这种气体会出现在有残留易燃易爆的废旧坑道中，但很容易通过气味鉴别（在开始的时候）。
Methane, comes from coal or other organic decomposition, often associated with atmospheric pressure and the lack of adequate through ventilation, lighter than air, found especially in blind rises or high places (empty shrink stopes) where there is stagnant air. This gas is flammable at low concentrations, explosive at higher ones and oxygen depleting at even higher concentration.
沼气（即甲烷气）：产生于煤或者有机物的分解，在常压下和缺少足够通风的条件下积聚。比重比空气轻。通常会在空气不流通的盲上斜或较高的地方聚集（如废弃的采矿场）。这种气体即使在浓度很低的情
