摘要
About 28 billion m3 of methane is emitted per year to the atmosphere from coal mining activities around the world.The mitigation and utilisation of the fugitive coal mine methane is very difficult because its concentration is very low and variable of 0.1%~1%, and it is contained in large air flow rate of 150~400 m3/s.This paper overviews the existing and developing technologies for the mitigation and utilisation of the fugitive mine methane, and then presents a ventilation air methane catalytic turbine (VAMCAT) technology we developed, which can be powered with about 1% methane in air.
