摘要:
煤田火区温室气体的排放速率在时间和空间上由于影响因素而存在差异，本研究在对目前气体排放通量研究基础上，采用空气动力学法对神府矿区活鸡兔火区排放CO2、CH4气体和风速、温度以及气压等环境参数进行原位监测，测试结果表明，CO2和CH4通量的变化规律一致，火区内CO2、CH4排放通量变化范围为3.88~30.46 mg/(m2·s)和0.12~1.36 mg/(m2·s)；通过相关性分析，环境因素对两种温室气体的排放影响很大，火区CO2、CH4的排放与风速、温度以及气压均呈显著正相关，相关性大小依次为风速＞温度＞气压，论证了所建的浓度梯度模型对煤田火区温室气体排放通量的适用性，进而为煤田火区有害气体污染治理提供了思路。
Abstract:
There are differences in time and space for the emission rate of greenhouse gas in coalfield fire area due to the influencing factors. Based on the studies of gas emission flux at present, the aerodynamic method was applied to carry out the in-situ monitoring on the emission of CO2 and CH4, as well as the environmental parameters such as wind speed, temperature and pressure in Huojitu coalfield fire area of Shenfu mining area. The results showed that the changing rules of CO2 and CH4 fluxes were consistent, and the changing range of emission flux for CO2 and CH4 was 3.88-30.46 mg/(m2·s) and 0.12-1.36 mg/(m2·s) respectively. Through the correlation analysis, it showed that the environmental factors have great impact on the emission of these two greenhouse gases. The emission of CO2 and CH4 has significant positive correlations with all the wind speed, temperature and pressure, and the correlation rank in descending order is wind speed, temperature and pressure. The applicability of concentration gradient model for emission flux of greenhouse gas in coalfield fire area was demonstrated. It provides a guideline for the pollution control of harmful gases in coalfield fire area.
