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.

煤矿瓦斯是一种严重的采矿危害和温室气体排放。该项目旨在通过在煤炭开采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。与密集瓦斯抽放相关的瓦斯爆炸和自燃风险将被定量评估和消除，以帮助矿山管理人员进行决策、优化设计和制定缓解计划。这将为采矿业提供重大利益，使其能够在安全工作场所维持生产承诺，同时通过捕获逃逸排放物并将其转化为有用的能源来解决环境问题。
