摘　　要：分析了射气测量的原理,阐述了射气测量的前提条件,就如何提高氡气的数据采集质量进行了研究,提出了射气测量的质量保证措施,得出了在一定的地质条件下射气测量在煤矿采空区中的应用效果较好的结论。The working principle of emanation measurement is analyzed. Based upon introduction of the prerequisite requirements of emanatign measurement the question that how to increase acquisition quality of radon data is discussed, at the same time corresponding quality assurance measures are proposed. Practice shows under a certain geological condition radon gas emanation measurement receive good application effect in coal mining-out area detection.
