　　瓦斯氣——瓦斯主要成分是甲烷(CH4)，它是無色無味無嗅可燃的氣體，爆炸條件：濃度在 5%~16%， 氧氣大于 12%，遇明火或者溫度 650℃至 750℃就引起爆炸，濃度 9.5% 爆炸威力最大；

　　Gas - The main component of gas is methane (CH4), which is a colorless, odorless, and flammable gas. The explosion conditions are: a concentration of 5% to 16%, oxygen greater than 12%, and it can cause an explosion when exposed to open flames or temperatures ranging from 650 ℃ to 750 ℃. A concentration of 9.5% has the highest explosive power;

　　當濃度大于 16% 時，燃燒不爆炸。主要由煤體或者腐爛植物產生，存在狀態：吸伏式和游離式。中國深埋在 2000 米以內的煤層中含煤層氣資源量達 30 － 35 萬億立方米，是世界上第三大煤層氣儲量國，煤層氣開發前景非常可觀。瓦斯氣在煤礦井下是煤礦工人第一天敵，由于地質、環境、空氣、工作場所復雜等多種原因，有一定濃度瓦斯，遇到明火就會爆炸，是礦難主要原因。為了從根本上控制重特大瓦斯爆炸事故的發生，國家煤礦安全監察局提出了瓦斯治理的十二字方針，即“先抽后采，監測監控，以風定產”。瓦斯發電既能變廢為寶促進生態建設，又能使瓦斯礦井安全得到進一步保證。在我國能源不足，

　　When the concentration exceeds 16%, combustion does not explode. Mainly produced by coal or decaying plants, it exists in two states: adsorbed and free. China's coal seams buried within 2000 meters contain 30-35 trillion cubic meters of coalbed methane resources, making it the third largest country in the world in terms of coalbed methane reserves. The development prospects of coalbed methane are very promising. Gas is the first natural enemy of coal miners underground. Due to various reasons such as geology, environment, air, and complex workplaces, there is a certain concentration of gas, which will explode when encountering open flames, making it the main cause of mining accidents. In order to fundamentally control the occurrence of major gas explosion accidents, the National Coal Mine Safety Supervision Bureau has proposed a twelve character policy for gas control, which is "pumping first and then mining, monitoring and monitoring, and determining production based on wind". Gas power generation can not only turn waste into treasure to promote ecological construction, but also further ensure the safety of gas mines. In our country, there is a shortage of energy,

　　并將制約經濟可持續發展的情況下，瓦斯資源的開發和利用，對緩解我國能源供應緊張狀況，意義十分重大。

　　Under the constraints of sustainable economic development, the development and utilization of gas resources are of great significance in alleviating the tight energy supply situation in China.
