完善碳排放清单,是进行减排工作的基础,为了查明煤田火区对大气碳排放的贡献量,以煤氧复合作用学说为理论基础,从不同的研究思路出发,提出了烧失煤量法和排放通量法两种火区碳排放量计算模型。在明确了模型中关键参数“释放因子”“排放系数α”“排放通量”“排放系数β”的具体含义的基础上,重点对各参数所对应的获取途径进行了研究论述:(1)释放因子通过在室内进行煤自燃模拟实验得出;(2)排放系数α通过煤岩吸附实验结合火区实地勘测得出;(3)排放通量通过对火区现场煤自燃气体排放及环境因素的实时监测得出;(4)排放系数β通过对遥感图像裂隙信息的提取得到。以我国乌达火区为实验区,两种计算模型进行了实际应用,对其可实现性进行了检验。
Improving carbon inventory is the basis of emission reduction work. In order to find out the contribution of fire area to the atmospheric carbon emission, based on the theory of complex action of coal and oxygen, starting from different research ideas, Method and Emission Flux Method for Calculating Carbon Emissions of Two Kinds of Fire Areas. On the basis of clarifying the concrete meaning of “emission factor”, “emission factor” and “emission factor” of key factors “release factor” in the model, the corresponding acquisition ways of each parameter are emphatically studied. (1) (2) The emission coefficient α is obtained through coal field adsorption experiment combined with the field survey of the fire area; (3) The emission flux through the coal spontaneous combustion gas emission in the fire area and the environmental factors (4) The emission coefficient β is obtained by extracting the fracture information of the remote sensing image. Taking the Wuda fire area in our country as the experimental area, two kinds of calculation models have been put into practical application and their feasibility has been tested.
