摘要
井工煤矿排放的温室气体为甲烷和二氧化碳,需要准确核算其排放量.本研究根据不同数据来源,提出新建、生产矿井的5 个甲烷和二氧化碳相对排放量的取值方法,比较了各方法的准确度,给出了按煤炭产量、通风系统回风量、瓦斯抽采系统抽采气量核算甲烷和二氧化碳逃逸排放量的公式,并建议现有监控系统都应配置二氧化碳浓度实时在线监测设备,实现温室气体排放量实时核算和显示.该研究为核算煤矿温室气体排放量提供了多种方法.
Abstract
The greenhouse gases emitted by underground coal mines are methane and carbon dioxide,methane and carbon dioxide emissions need to be accurately accounted.According to different data sources,fivecalculation methods for relative emissions of methane and carbon dioxide in newly built and producing coal mines are proposed.The accuracy of each method is compared,and formulas for calculating the escape emissions of methane and carbon dioxide are given according to the coal output,the return air volume of ventilation system and the air volume of gas drainage system.It is suggested that the existing monitoring system should be equipped with real-time online monitoring of carbon dioxide concentration to realize real-time calculation and display of greenhouse gas emissions.This study provides a variety of methods for underground coal mine accounting of greenhouse gas emissions.
