摘要
分析了露天煤体自然发火的原因和特点，进行了煤的氧化试验和野外煤堆自燃的模拟试验，通过对试验测试数据的分析讨论了煤体自燃发生的过程、温度场及CO排放量等的变化规律.所得结果对分析与预测煤体的自燃进程、防治露天煤体的自燃火灾等具有重要意义.
The reason and features of spontaneous combustion of ground coa l seams and co al piles were discussed. The oxidation test of coal sample s and the simulation experiment of spontaneous combustion of a ground coal pile h ave been made. The spontaneous progress and the changes in CO content a nd temp erature in this process were investigated. The rese arch results are important for the predication and prevention of coal spontane ous combustion of ground coal.
