Maximise goaf gas drainage for safe coal extraction and emissions reduction

煤矿瓦斯是一种严重的矿山灾害和温室气体排放。该项目旨在通过最大限度地提高采煤过程中的瓦斯捕获量来提高采矿安全。这将通过现场数据反分析、耦合多物理模型和随机风险评估来实现。将对与密集瓦斯抽放相关的瓦斯爆炸和自燃风险进行量化评估和消除，以帮助矿山管理人员决策、优化设计和缓解规划。这将使采矿业在维持安全工作场所的生产承诺的同时，通过捕获逃逸排放以转化为有用的能源来解决环境问题，这将为采矿业带来重大好处。

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.
