【摘要】：为了研究林南仓矿采空区自然发火遗煤耗氧速率的影响因素,采用了控制变量法研究出煤的变质程度、遗煤环境对耗氧速度的影响,同时采用Matlab软件对这两个因素同时进行回归分析,建立遗煤的耗氧速度耦合模型。并根据《煤自燃倾向性色谱吸氧鉴定法》的实验计算出的耗氧速率与模型中的条件及结果几乎一样,结果表明,氧气浓度与耗氧速率是正相关关系,温度与耗氧速率是指数关系,温度和浓度耦合是显著线性回归的。
[Abstract]:In order to study the influence factors on the rate of oxygen consumption of coal from spontaneous combustion in the mined-out area of Linnan Cang Mine, the metamorphism degree of coal and the influence of coal environment on the rate of oxygen consumption were studied by using the control variable method.At the same time, the regression analysis of these two factors was carried out by using Matlab software, and the coupling model of oxygen consumption velocity of coal was established.The oxygen consumption rate calculated by the method of coal spontaneous combustion tendency chromatographic oxygen absorption identification is almost the same as the conditions and results in the model. The results show that the oxygen concentration is positively correlated with the oxygen consumption rate.The relationship between temperature and oxygen consumption rate is exponential, and the coupling of temperature and concentration is significantly linear regression.
