摘　　要：为明确郭家湾煤矿的火源位置及范围,对整个井田范围进行地表勘探,标记出各个区域的疑似火区,采用同位素测氡法对整个矿区疑似火源区进行探测。结果表明,整个井田范围内共探测出9处氡值异常区域,其中有6处异常区集中于小窑口附近,附近漏风通道中有大量水汽逸出。根据现场实测结果及地形推测,小窑口漏风为煤矿的主要发火原因。In order to clarify the location and scope of the fire source in Guojiawan Coal Mine,surface exploration was carried out on the whole mine field,and suspected fire areas in each area were marked.Then,the suspected fire source areas in the whole mine area were detected by isotope radon measurement method.The results showed that 9 abnormal radon value areas were detected in the whole well field,among which 6 abnormal areas were concentrated near the mouth of the small kiln,and a large amount of water vapor escaped from the nearby air leakage channel.According to the results of field measurement and topography,the air leakage at the mouth of small kiln is the main cause of ignition.
