摘　　要：地质雷达由于能够直接识别地下目标体,井下探测快速,不影响生产,分辨率高,在煤矿瓦斯灾害防治方面有较大的优势.本文基于地质雷达基本原理,探讨井下探测工艺,分析井下数据处理的方法,对井下瓦斯富集区异常特征进行分析,并与其他地质异常进行了比较.研究结果表明若在传播距离范围内存在明显的回波异常,则有可能存在瓦斯富集区.随着研究的深入,地质雷达有望突破瓦斯富集区探测的难题.Because the Ground Penetrating Radar is able to directly identify the underground object, detection of underground is very fast, not effect to production and have high resolution, it has greater advantage in coal mine gas disaster prevention. This paper based on the basic principle of Ground Penetrating Radar, discussed the detection technology of coal mine, analysis the method of coal mine data processing and the anomalous characteristics of gas enrichment area, compared to other geological anomalies. The research results show that if there exist obvious abnormal ret in the propagation distance range, there may exist gas enrichment area. With the development of research, Groand Penetrating Radar is expected to break through problem of gas enrichment area detection.
