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200MHz^1GHz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。
Coal-rock interface detection principle using ground penetrating rader 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-1GHz 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.
