Utilization and Mitigation of Ventilation Air Methane in Coal Mining: A Focus on Turkey
Abstract: Ventilation Air Methane (VAM), a byproduct of underground coal mining, is a significant source of methane emissions and a potential energy resource. VAM is typically released at low concentrations, ranging from 0.1% to 1.5%, making it challenging to capture and utilize effectively. This article explores methane enrichment technologies, focusing on the weak eddy and free diffusion methods to increase VAM concentrations. These techniques have shown promise in enhancing methane capture …
