【摘要】：研究目的:露天煤矿能源消耗产生的碳排放是主要受控排放源,对于减缓温室气体具有重要意义。研究方法:采用IPCC碳排放计算方法,确定露天煤矿区碳排放因子,构建露天煤矿区碳排放核算模型,确定直接碳排放、间接碳排放的计量模型。以平朔矿区三座大型露天煤矿为例,核算2011—2015年期间由于燃油、炸药、逸散、电力产生的碳排放。研究结果:2011—2015年期间平朔矿区三座大型露天煤矿土地损毁碳排放量高达591.21万t。燃油、爆破、逸散、电力产生的碳排放总量分别为302.60万t、16.30万t、203.66万t、68.65万t。研究结论:通过缩短运输运距、优化坑下采剥运输道路设计、提高机械使用效率、优化车铲匹配、减少电铲待装时间等措施,能够减缓大型露天煤矿土地损毁碳排放量。
[Abstract]:Objective: carbon emission from energy consumption in opencast coal mine is the main controlled emission source, which is of great significance to reduce greenhouse gas. Methods: the carbon emission factor of open pit coal mine is determined by IPCC carbon emission calculation method. The carbon emission accounting model of open pit coal mine area is constructed, and the measurement model of direct carbon emission and indirect carbon emission is determined. Taking three large opencast coal mines in Pingshuo mining area as an example, accounting for fuel oil, explosives and dissipation during 2011-2015, Carbon emissions from electricity. The results of the study were as high as five million nine hundred and twelve thousand and one hundred tons of carbon from three large opencast coal mines in Pingshuo mining area between 2011-2015. The total carbon emissions produced by electric power are three million twenty-six thousand t, 163,000 t, two million thirty-six thousand and six hundred t and 686,500 t respectively. The research conclusions are as follows: by shortening the transportation distance, optimizing the design of underground pit stripping transportation road, improving the efficiency of mechanical use, optimizing the matching of the scoop, and reducing the waiting time of the electric shovel, etc. Can reduce the large open-pit coal mine land damage carbon emissions.
