　　瓦斯气——瓦斯主要成分是甲烷(CH4)，它是无色无味无嗅可燃的气体，爆炸条件：浓度在 5%~16%， 氧气大于 12%，遇明火或者温度 650℃至 750℃就引起爆炸，浓度 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;

　　当浓度大于 16% 时，燃烧不爆炸。主要由煤体或者腐烂植物产生，存在状态：吸伏式和游离式。中国深埋在 2000 米以内的煤层中含煤层气资源量达 30 － 35 万亿立方米，是世界上第三大煤层气储量国，煤层气开发前景非常可观。瓦斯气在煤矿井下是煤矿工人第一天敌，由于地质、环境、空气、工作场所复杂等多种原因，有一定浓度瓦斯，遇到明火就会爆炸，是矿难主要原因。为了从根本上控制重特大瓦斯爆炸事故的发生，国家煤矿安全监察局提出了瓦斯治理的十二字方针，即“先抽后采，监测监控，以风定产”。瓦斯发电既能变废为宝促进生态建设，又能使瓦斯矿井安全得到进一步保证。在我国能源不足，

　　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,

　　并将制约经济可持续发展的情况下，瓦斯资源的开发和利用，对缓解我国能源供应紧张状况，意义十分重大。

　　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.
