摘要
为了客观的分析井工矿井煤炭开发中CH4(瓦斯的主要成分)排放的影响因素,在分析瓦斯形成过程及赋存条件的基础上,结合我国井工开采矿井生产工艺、抽采现状,构建了由煤层瓦斯含量因素、开采技术因素、瓦斯抽采状况及瓦斯残留状况四个子系统构成的井工矿井煤炭开发中CH4排放影响因素综合评价指标体系。该指标体系由16个二级指标构成,具有科学、全面、指标较易获取的特点,有助于分析我国井工矿井煤炭开发中的减排潜力,为制定相应的CH4减排措施提供依据。
In order to evaluate the factors that influence CH4( the main component of the gas) emissions during the underground coal mining objectively,a comprehensive evaluation index system with 4 first- class index of influence factors of CH4emission in underground coal mining is established,including coal seam gas contents factor,mining technical factor,gas extraction conditions and gas residues. The index system consists of 16 second- class index which is scientific,comprehensive,easy to get,and It can be used to analyze the potential mitigation of CH4emissions from China's underground coal mining and provide important theoretical foundation for regulating measures for CH4reduction.
