多频无线电波透视技术在演马庄煤矿中的应用
|
摘要
无线电波透视在演马庄矿应用中,高频的1.5MHz对异常响应较明显,但衰减较快,低频的0.3MHz、0.5MHz衰减较慢,但对异常响应稍弱,3个频率的综合应用效果更佳。多频无线电波透视利用多频同步分时探测工艺,实现了3个频率的同时探测,降低了工作量,提高了工作效率。便于综合利用3个频率的探测成果研究回采工作面内部地质异常的发育情况,提高了解释精度,为煤矿安全生产提供了技术保障。
In the application of the radio wave perspective in the Yanmazhuang Coal Mine, the high frequency(1.5 MHz) has more obvious response to the abnormal response, but the attenuation is faster. The attenuation of low frequency(0.3 MHz, 0.5 MHz) is slower, but the abnormal response is weaker. So the comprehensive application of the three frequencies is better. The multi-frequency radio wave penetration technology utilizes the different frequency radio wave in turn to realize the simultaneous detection of three frequencies, which reduce the workload and improve the work efficiency. It is easy to make comprehensive use of the three frequency detection results to study the development of the internal geological anomalies in the mining face, and improve the interpretation accuracy and provide technical support for the safety production of the coal mine.
