Abstract: Nowadays, the worries about energy crisis and environment problems are growing. Energy crisis is one of the fatal threats to human development, and the environment problems are mainly due to the unreasonable energy consumption and energy structure. Therefore, energy consumption structure is one of the important indicators to measure the development of a nation. With huge proved reserves of shale gas, China can develop its technologies and construct more wells by learning from the North America. Shale gas is a kind of pure natural gas and has diverse applications. However, its compositions are different due to different geological environments, so it is crucial to know its compositions. This paper briefly introduces the technologies for integrated utilization of shale gas

Key words: explosion, mixture, maximum experimental safe gap/MESG, minimum ignition current ratio/MICR
