煤升温氧化过程中Rn的析出与CO、CO_2、CH_4相关性实验研究

Separation of Rn from coal oxidation at rising temperature and a relevant study on CO,CO_2 and CH_4

通过对煤炭自燃过程进行实验模拟,得到煤升温氧化过程中,各指标气体及氡的浓度随温度升高的变化情况。对各气体浓度随温度的变化曲线进行拟合比较后得出:在煤升温氧化过程中,Rn的析出与CO、CO2、CH4有着一定的相关性,并利用模糊数学相关性检验法对其相关性进行了判定。

Based on an experimental simulation of the process of spontaneous combustion of coal, detailed infor mation about the concentration variations of index gases and radon released change with the temperatures. A corn parison of the curves of concentration changes of all gases with the temperature shows that in the course of coal oxi dation with rising temperatures, separation of Rn and separation of CO, CO2 and CH4 are somewhat interrelated. Then, a fuzzy mathematics dependent check-up is used for related judgment.
