井工煤矿全生命周期甲烷捕集核算及减排路径

Capture accounting and emission reduction of methane in the whole life cycle of underground coal mine

甲烷减排是我国碳减排目标的重要组成部分,建立甲烷捕集核算体系是实现甲烷减排的前提。以甲烷近零排放为目标,结合《国家温室气体清单指南:IPCC—2019》和煤炭企业温室气体排放核算国家标准,提出了井工煤矿全生命周期中地质勘探、煤炭开采、矿后活动和煤矿废弃各阶段甲烷捕集的具体核算方法,构建了井工煤矿全生命周期甲烷捕集核算模型。在此基础上,提出了井工煤矿甲烷减排路径及其实施方案。研究结果可为井工煤矿甲烷治理与低碳发展提供指导。

Methane emission reduction is crucial to realizing China's carbon emission reduction goals,where a methane capture accounting system is the prerequisite.With the aim to realize near-zero methane emissions,we thereby propose a specific accounting model for methane capture in the whole life cycle of underground coal mines from geological exploration,coal mining to post-mine activities and coal mine discarding by drawing on the“National Greenhouse Gas Inventory Guidelines:IPCC-2019”and the national standards for accounting for greenhouse gas emissions of coal enterprises.In particular,we propose methods for methane emission reduction and discuss detailed plan for its implementation.The study could offer references for methane control and low-carbon development in underground coal mines.
