摘要: 介绍了探地雷达探测煤岩界面的原理,探讨了利用探地雷达技术进行煤岩界面探测的可行性与实用性,经理论分析,证明200 MHz~1 GHz的雷达天线可实现绝大多数的煤岩界面探测;采用LTD-2100探地雷达在郭庄煤矿进行了相关试验,结果表明,400 MHz雷达天线可实现气煤-砂岩界面的探测,且误差较小。Abstract: Coal-rock interface detection principle using ground penetrating radar was introduced. Feasibility and practicability of using ground penetrating radar technology to detect coal-rock interface was discussed. The radar antenna with frequency of 200 MHz-1 GHz was proved to realize most of coal-rock interface detection through theoretical analysis. The experiment was taken by use of LTD-2100 ground penetrating radar in Guozhuang Coal Mine. The experimental results show that radar antenna with frequency of 400 MHz can realize detection of gas coal-sandstone interface with a small error.
