五家沟矿地质雷达地质探测应用研究

Study on the Application of Geological Radar Detection in Wujiagou Mine

地层中隐伏的导、含水构造是巷道掘进时发生矿井突水事故的重要原因,极大地威胁了煤矿的安全生产。对掘进巷道前方及周边进行探测,掌握掘进巷道地层中隐伏的异常地质情况具有重要的意义。论文首先介绍了基于地质雷达方法的井下超前地质探测方法和原理,然后从实际工程应用出发,对五家沟矿5204采空区进行地质雷达探测。数据处理后,基于时间剖面和频率剖面复合解释技术对该巷道异常情况进行解释,探明了5204采空区位置,确定了煤柱厚度,降低了采空区积水对巷道的威胁程度。

The formation of the guide, hidden water bearing structure is an important reason of mine water inrush accident tunnel, a great threat to coal mine safety production. To detect the roadway ahead and surrounding, has important significance on mastering abnormal geological conditions of buried roadway formation. This paper first introduces the method and principle of the underground geological exploration based on geological radar, and then starting from the practical application of geological radar detection in 5204 goaf in Wujiagou mine. After data processing, paper explains abnormal situation by the interpretation of composite roadway section and frequency profile, proves the 5204 goaf location, determines the pillar thickness, to reduce threat level of the goaf waterlogging on roadway.
