摘要
基于生命周期法和井工煤炭开采工艺流程分析了井工煤炭开采全生命周期的碳排放边界和碳排放源,构建了煤炭开采全生命周期的碳排放核算模型,并结合煤炭生产企业的实际生产情况进行案例分析。结果显示,甲烷的逃逸和电力的消耗是煤炭开采温室气体排放的最主要因素;煤炭开采的全生命周期内,维持矿井正常运行的基础电力消耗是最大的耗电项目,掘进和回采设备在电力消耗中也占有较大比重。最后提出了煤炭生产企业的低碳发展对策。
The carbon emission boundary and carbon emission sources in the whole life cycle of underground coal mining were analyzed based on the life cycle approach and underground coal mining process, a carbon emission accounting model was constructed for the whole life cycle of coal mining, and finally an example study was conducted. The results show that, the methane escape and electricity consumption are the most important factors of greenhouse gas emissions from coal mining;the basic electricity consumption to maintain the normal operation of the mine is the largest power consumption item in the whole life cycle of coal mining, and the excavation and mining equipment also occupy a large proportion in the electricity consumption. Finally, the low carbon development countermeasures of coal production enterprises are proposed.
