摘　　要：为了寻找采空区内部氧化自燃最危险区域及其与工作面的距离,提出了采空区氧化中心确定原理及方法。介绍了采空区氧化中心的定义及意义,分析了采空区氧化中心的影响因素。采空区氧化中心包括氧化中心浓度和氧化中心距离,氧化中心浓度能清楚描述采空区内部氧化自燃最危险区域的危险程度,氧化中心距离能直观反映采空区内部氧化自燃最危险区域与工作面的距离,二者不受人为主观因素影响。应用实例表明,通过比较采取防灭火措施前后氧化中心距离和氧化中心浓度的变化情况,可以较好地评估所采取的防灭火措施的实施效果。In order to find out the most dangerous oxidation and spontaneous combustion area in the gob and its distance to the working face,the principle and method for determining the oxidation center in the gob was proposed. This paper described the definition and meaning of the oxidation center in the gob,and analyzed its influence factors. The oxidation center in the gob included the concentration and distance of the oxidation center,the concentration of the oxidation center can clearly describe the risk degree of the most dangerous oxidation and spontaneous combustion area in the gob,and the distance of the oxidation center can directly reflect the distance from the most dangerous oxidation and spontaneous combustion area to the working face,and they were not affected by the human subjective factor. The application showed that better evaluation on the effect of the fire prevention and control measures can be made by comparing the change of the distance and concentration of the oxidation center before and after the implementation of the fire prevention and control measures.
