Influence of Coal Gas on Atmosphere Environment and Its Countermeasures

China is a country with high coal production and consumption. Being the main energy resource of China, coal has provided a reliable energy supply for the sustainable development of the countries national economy. Coal in China has made a great contribution for the national economic development, but it has also caused a negative influence on the ecological environment in China. This paper introduces the characteristics and present status of coal mining and production in China. It analyses the effect of coal gas on the atmospheric environment. It is suggested that developing and utilizing coal-bed methane is not only the basic path and method to solve the air pollution and greenhouse effect of methane induced by coal gas, but also the ultimate way to reduce the safety accidents of coal gas during coal mining.
