摘要
采用频率谐振技术对深埋煤层采后覆岩移动特征进行研究。介绍了频率谐振技术的原理和工程背景,设计了检测线和检测点布置方案并现场实施,得到了深埋煤层覆岩移动的时空特征。研究结果表明,频率谐振技术是一种有效的深地探测方法,研究成果可用于指导采场压力控制。
Frequency resonance technology is used to study the characteristics of overburden movement in deep coal seam after mining.The principle of frequency resonance technology and engineering background are firstly introduced,then the layout of test lines and test points is designed and implemented.The spatio-temporal characteristics of overburden movement in deep coal seam.The results show that the frequency resonance technique is an effective method of deep sounding,and the research results can be used to guide the control of mine pressure.
