【 摘 要 】

As is known to all, the methane concentration in the ventilation air of coal mine is very low, which cannot be directly utilized, with a huge total amount of methane, resulting in significant greenhouse effect. Data show that China's annual greenhouse gas effect from methane released into the atmosphere from ventilation air methane (VAM) is about 200 million tons of carbon dioxide equivalent. Therefore, it is of great significance to study how to increase the concentration of methane economically and to make energy utilization. In particular, the Paris agreement put forward by the 21st conference of the parties to the United Nations framework convention on climate change recently requires the world to reach the peak of greenhouse gas emissions as soon as possible. The Chinese government has also made the commitment of reducing emissions from climate change. The only way for the coal industry to survive and develop is to popularize the technology of the scavenging gas concentration, destruction and utilization. This paper systematically summarizes the realization approach, technical objective and current situation of the utilization technology of VAM enrichment technology at home and abroad, and prospects its application prospect and new research direction.
