摘　　要：为了研究井下高地温环境对煤自燃的影响,采用程序升温试验装置对煤样预先40℃恒温氧化后进行程序升温试验,通过对比常温下进行的试验过程,得出高温环境下煤体的气体产生率、耗氧速率及放热强度高于常温下氧化煤体,自燃危险性有所增加。Temperature - programmed experimental device is carried out to research the effect of high ground temperature environment on coal spontaneous combustion characteristics. Coal sample is oxidized in the constant temperature of 40 ℃, and then tested by tem- perature -programmed method. By comparing experiment process in normal temperature, the oxygen consumption rate, gas generation rate and exothermal intensity in the high temperature are higher than that in normal temperature. And the risk of spontaneous combus- tion increased
