【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。
[Abstract]:Selecting 310kHz as the working frequency of YDT175 radio wave fluorometer and adopting appropriate anti-interference method, the hidden faults in 61101 first mining face of Tangjiahui coal mine in Zhunger coalfield were detected and tested. The CT software of radio wave perspective is used to retrieve and display the collected data. Results three electromagnetic wave attenuation zones were found in the 770 ~ 1 370 m section of the return air roadway of the working face, which was interpreted as a fault. According to the existing geological data and the actual exposure of the roadway, there are three normal faults in these three attenuation zones, which indicates that the selection of appropriate radio wave perspective frequency can reliably detect the concealed geological anomalies in the coal face. Radio wave perspective method is an effective technology to ensure safe and efficient production of mine face.
