Research and application of reflected channel wave imaging in underground mine

为了查明煤矿井下巷道侧帮隐伏构造的分布情况,在介绍槽波探测理论及方法的基础上,基于槽波资料特点,系统分析了反射槽波资料成像的主要难点,并提出有针对性的技术措施和成像方法。最后,通过综合分析三维三分量(3D3C)正演模拟结果和工程实例探采验证情况后认为:利用Z分量槽波数据,采取有针对性的处理及成像方法,能够实现煤矿井下反射槽波探测,并取得良好的探测效果。

In order to find out the distribution of concealed structure in the side of underground coal mine roadway,this paper systematically analyzed the main difficulties in imaging technique of reflected channel wave data based on the theory and method of channel wave detection and the characteristics of channel wave data,and proposed technical measures and imaging methods. Finally,according to the comprehensive analysis of 3D3 C forward modeling and the comparison results with engineering example,it was considered that by using the Z component channel data with related processing and imaging methods,reflected channel wave detection was able to be achieved with favorable results.
