中文摘要：

为研究煤油共生矿区煤自燃特性,利用煤氧化动力学测定系统,测试原煤样与含油煤样。根据煤自燃倾向性判定标准、耗氧速率及煤氧复合反应理论,分析试验结果。以铜川下石节煤矿煤样和原油样品（煤岩渗出的油,文中称为原油）为例,向原煤样中添加一定量的原油制备含油煤样,通过试验获得原煤样与含油煤样低温阶段（30--240℃）的自燃特性参数。研究结果表明,2种煤样自燃倾向性等级均为自燃,但原煤样更接近于易自燃;相同温度条件下含油煤样的耗氧速率、CO与CO2的生成量均比原煤样小;在低温氧化阶段,造成上述结果的主要原因是,原油充填了煤样的部分空隙和孔隙,阻碍了煤氧复合反应。

英文摘要：

In order to study the spontaneous combustion of coal in coal-oil coexistence area, original coal samples and coal samples added with oil were tested by using of a coal oxidation kinetics testing method system. The test results were analyzed based on the spontaneous combustion tendency identification stand- ard, oxygen consumption rates and reaction of coal oxidation theory. The coal samples were collected from Tongchuan Xiashijie coal mine and the oil was also collected from the same coal mine. The spontaneous combustion characteristic parameters of both coal samples at low temperature （30 - 240 ~C ） were tested by using the test system. The results show that spontaneous combustion tendency of coal samples belongs to spontaneous combustion while original coal sample tends to easy spontaneous. Simultaneously, the oxygen consumption rates and the generation column （include CO and CO2 ） of coal sample containing oil are smaller than original coal sample at the same temperature. In addition, the reason of these results is that oil filling in part of coal sample porosity and pore obstructs the reaction of coal and oxidation.
