基于全生命周期法的矿用柴油重卡碳核算

矿用柴油重卡因工作任务量大和工作环境恶劣，导致其碳排放量巨大。从使用矿用柴油重卡的企业角度出发，采用全生命周期法，理清了矿用柴油重卡全生命周期各个阶段的碳排放量及影响碳排放的因素，建立了矿用柴油重卡碳核算模型。以内蒙古某煤矿4种柴油重卡为案例，对矿用柴油重卡全生命周期碳排放量进行了核算，分析了核算结果，并从车辆重量与经济性角度，分析比较了几种车辆的单位重量排放量和单位价格排放量。结果表明：矿用柴油重卡全生命周期碳排放量由车辆重量和燃料消耗量共同作用，其中燃料消耗量占绝大比重。综合考虑节能减排和经济性，重量为156 t和85 t的车辆是最佳选择，煤矿企业可适当提高该类车辆的占比。在保证工作量的情况下，将138 t和65 t车辆代替为156 t和85 t的车辆，全生命周期内可减少1.275×10⁵ t 的碳排放量，节省9 936.704 万元的花费。本研究结果可为重卡企业开展节能减排工作提供参考。

Carbon accounting and case analysis of mining diesel heavy trucks based on full life cycle method

In recent years, carbon emission has attracted wide attention from all over the world. Mining diesel recaine, with its large work volume and harsh working environment, leads to huge carbon emission. However, there are few studies on its carbon emission. Based on this, from the perspective of enterprises using mining diesel heavy trucks, a carbon accounting model for mining diesel heavy trucks is established by adopting the whole life cycle method, aiming to clarify the carbon emissions of mining diesel heavy trucks at each stage of the whole life cycle and the factors affecting carbon emissions. Meanwhile, taking four kinds of diesel heavy trucks in a coal mine in Inner Mongolia as an example, the life cycle carbon emissions of mine diesel heavy trucks were calculated, and the calculation results of four kinds of vehicles were analyzed. From the perspective of vehicle weight and economy, emissions per unit weight and emissions per unit price of several vehicles are analyzed and compared. The results show that the carbon emissions of the whole life cycle of mining diesel heavy trucks are the result of the combined action of vehicle weight and fuel consumption, of which fuel consumption accounts for the vast majority. Considering energy saving, emission reduction and economy, vehicles weighing 156 tons and 85 tons are the best choices, and coal mining enterprises can appropriately increase the proportion of such vehicles. Under the condition of ensuring the amount of work tasks, replacing 138-ton and 65-ton vehicles with 156-ton and 85-ton vehicles can reduce carbon emissions by 1.275×105 t and save 99 367 040 yuan in the whole life cycle. The results of this study can provide reference for enterprises to carry out energy conservation and emission reduction work.
