摘　　要：煤矿综采工作面的回采工艺在获得煤炭资源的同时也消耗了大量的能量,而这些能量的消耗也伴随着二氧化碳的排放。为了从碳排放的角度评估煤矿在地下开采过程对环境的影响,本文基于生命周期评价方法,以综采工作面为主要研究对象,研究煤矿地下开采过程中各个工艺环节的碳排放及能耗,建立综采工作面碳排放计算模型,并以新疆人和矿A303工作面为工程背景,对该工作面回采过程中的碳排放进行计算和分析,对相关碳排放及能耗占比高的环节提出改进建议。研究结果可推进煤矿节能减排,对“碳达峰、碳中和”背景下煤矿的低碳生产具有重要意义。The mining technology of fully mechanized coal mining face consumes a lot of energy while obtaining coal resources,and these energy consumption is also accompanied by carbon dioxide emissions.In order to evaluate the impact of coal mine underground mining process on the environment from the perspective of carbon emissions,v Based on the life cycle assessment method,this paper takes the fully mechanized mining face as the main research object,studies the carbon emissions and energy consumption of each process link in the underground mining process of coal mine,and establishes the carbon emissions calculation model of the fully mechanized mining face.Taking the A303 working face of a mine in Xinjiang as the engineering background,the carbon emissions in the mining process of the working face are calculated and analyzed,and suggestions for improvement are put forward for the links with high carbon emissions and energy consumption.The research results can promote energy conservation and emission reduction in coal mines,which is of great significance to the low-carbon production of coal mines under the background of’carbon peak,carbon neutralization’.
