摘要：

为探究复杂条件下地表碳通量对地下遗煤自燃的响应机制,通过长期监测阜新海州露天矿采空区上覆地表碳通量、土壤温度、地表裂缝、环境风速、土壤湿度等数据,并结合现场试验,研究遗煤燃烧与地表碳通量的相关性,分析地表裂缝、环境风速、土壤湿度等因素对地下煤自燃-地表碳通量的影响特征。结果表明:地下遗煤燃烧是触发地表碳通量异常响应的根本因素,碳通量与土壤温度分布呈正相关;裂缝是影响地表碳通量分布的主要因素,环境风速与地表碳通量基本呈正相关,地表碳通量一般不受土壤湿度影响,但受降雨影响较大。

Abstract:

In order to explore the response mechanism of spontaneous combustion of underground coal and surface carbon flux under complex conditions, the surface CO₂ flux, soil temperature, fissure, environmental wind velocity and soil humidity in Fuxin Haizhou open-pit mine were monitored for a long time. Field tests, data analysis and other methods were applied to study the correlation between the underground coal spontaneous combustion and surface CO₂ flux. The influence of surface fissure, environmental wind velocity and soil humidity on the response mechanism of underground coal spontaneous combustion-surface carbon flux were analyzed. The results show that underground coal combustion is the fundamental factor triggering the abnormal surface carbon flux response. The surface CO₂ flux is positively correlated with the surface soil temperature distribution. Surface fissure is the main factor affecting the surface CO₂ flux distribution. The environmental wind speed is positively correlated with the surface CO₂ flux. The surface CO₂ flux response is generally not affected by soil humidity, but it is greatly affected by rainfall.

Key words: goaf, combustion of residual coal, soil surface CO₂ flux, correlation analysis, surface fissure, environmental wind velocity, soil humidity
