Abstract: Based on the characteristics of gas collected from Duanwang Coal Group, combined with the development of coal mine and the thermal energy demand of coal mine, this paper puts forward and selects the low concentration gas utilization scheme, designs the low concentration gas water mist transmission process, introduces the gas power generation system configuration And waste heat recovery and utilization system, while the low concentration of gas power generation proposed optimization recommendations. The results show that the project can create a certain economic benefits, improve business income, while bringing a good environmental benefits, play a role in protecting the environment.
