试样自热的观测是研究矿岩自燃倾向的试验内容之一。五十年代,苏联学者曾设计制造了一种硫化矿石自热试验装置;七十年代,日本、美国学者也设计制造了测定煤的自热试验装置;在我国,长沙矿山研究院曾研究过胶状黄铁矿的自热。但是,矿岩由低温氧化、自热到自燃是一个极其复杂的物理化学过程,除了外界条件的影响以外,内在因素较多。几年来,我们在从
The observation of the self-heating of the sample is one of the experimental contents for studying the spontaneous combustion tendency of the ore rock. In the 1950s, Soviet scholars designed and manufactured a self-heating test device for sulfide ores. In the 1970s, Japan and the United States also designed and manufactured self-heating test devices for measuring coal. In China, Changsha Institute of Mines studied plastic Pyrite self-heating. However, the ore rock is oxidized from low temperature, self-heating to spontaneous combustion is an extremely complex physical and chemical process, in addition to the impact of external conditions, there are many internal factors. In recent years, we are from
