摘　　要：选择310 k Hz作为YDT175型无线电波透视仪的工作频率,采取恰当的抗干扰方法,对准格尔煤田唐家会矿井61101首采工作面隐伏断层进行了探测试验,使用无线电波透视CT软件对采集数据进行反演处理与显示。结果在工作面回风巷770~1 370 m段发现3处电磁波衰减带,解释为断层。经已有地质资料以及巷道实际揭露验证,这3处衰减带内的确存在3条正断层,说明选择适当的无线电波透视频率能够较可靠地探测工作面隐蔽地质异常体,无线电波透视法是保障矿井工作面安全高效生产的有效技术。The concealed faults in61101first coalface of Tangjiahui coal mine in Zhungeer coalfield were probed byusing YDT175type radio wave perspective instrument with310kHz as the working frequency,and by taking appropriateanti-jamming methods.The experimental data was processed and displayed by using composite curve methodand the CT imaging method.The result shows that there are three high absorption and attenuation bands at770~1370m of61101coal face gateway,and these high absorption and attenuation bands were interpreted as faults,They havebeen verified by the existing geological data and the actual exposure to the roadway that three normal faults exist inthree high attenuation bands.These facts illustrate that selecting the appropriate radio waves perspective frequencycan reliably detect the hidden geological abnormal body,radio wave perspective method is the effective technology toensure the face mining in safety and high efficiency.
