Revolutionary gas drainage tech boosts coal mine safety and efficiency.
Gas drainage in low permeability coal seams is crucial for safety and productivity in mines. A study in the Yangquan mine area used a numerical model to improve gas drainage. They found that implementing the technology increased gas drainage rates by 30-40%. The study analyzed gas movement, stress changes, and gas release during coal extraction to optimize drainage parameters. The research shows that this approach can effectively enhance gas drainage in low permeability coal seams.
