确定煤堆积体及通过其渗透的空气之间的热交换和质量交换参数,对于改善现有的防止内因火灾方法和拟定新方法具有重要的意义。上述参数既可确定各阶段形成的条件又可确定煤自燃整个过程发展的时间。根据干燥理论的基本规律,这些参数还表示氧化煤在内因火灾发生之前的干燥动力学的规律。 Determining the heat exchange and mass exchange parameters between the coal stack and the air permeating through it is of great importance to improving the existing methods of preventing internal fires and developing new methods. The above parameters not only determine the conditions of each stage but also determine the spontaneous combustion of coal throughout the development process. According to the basic laws of the drying theory, these parameters also indicate the law of the kinetics of drying kinetics of the oxidized coal before the internal fire occurs.
