Maximise goaf gas drainage for safe coal extraction and emissions reduction

煤矿瓦斯是一种严重的开采危害和温室气体排放。该项目旨在通过在采煤过程中最大限度地捕获气体来提高采矿安全。这将通过现场数据反分析、耦合多物理场建模和随机风险评估来实现。将定量评估和消除与瓦斯密集抽放相关的瓦斯爆炸和自燃风险，以帮助矿山管理者进行决策、设计优化和减灾规划。这将为采矿业在安全的工作场所维持生产承诺提供重大好处，同时通过捕获逃逸的排放物转化为有用的能源来解决环境问题。

Coal mine methane is a serious mining hazard and greenhouse gas emissions. This project seeks to enhance mining safety by maximising gas capture during coal extraction. This will be achieved through field data back-analysis, coupled Multiphysics modelling, and stochastic risk assessment. Gas explosion and spontaneous combustion risks associated with intensive gas drainage will be quantitively assessed and eliminated to help mine managers’ decision making, design optimisation, and mitigation planning. This will provide significant benefit for the mining industry in maintaining production commitments in a safe workplace while addressing environmental concerns by capturing the fugitive emissions to be converted into a useful energy resource.
