Mine Methane

Underground longwall mining in gassy multi-seam environments can cause excessive gas emissions in underground workings, leading to significant longwall production delays. Effective gas management in such an environment must recognise the mechanics of longwall mining and its impact on gas reservoirs and gas migrations, particularly in low permeability conditions.

• Reservoir condition characterisation
• Multi-seam gas emission prediction
• Optimal gas drainage design for emission mitigation
• Integrated extraction of coal and methane
