槽波探测技术在济宁阳城煤矿的应用
|
摘要
回采工作面内的隐伏构造影响煤矿开采和安全生产,槽波技术是井下查明工作面隐伏构造的有效手段。本文将槽波技术应用于济宁阳城煤矿,分析了该矿槽波发育情况和波场特点,槽波成像采用振幅衰减系数CT成像技术。结果表明槽波对断层构造反映敏感,探测准确度高,振幅衰减系数成像方法成像精度高,阳城煤矿槽波发育好,适于应用槽波技术。
The concealed structure in the mining face affects coal mining and safe production, and the in-seam wave technology is an effective means to find the hidden structure of the working face underground. In this paper, the in-seam wave technology is applied to the Yangcheng coal mine in Jining. The development state of in-seam wave and the characteristics of the wave field are analyzed. The in-seam wave imaging uses the amplitude attenuation coefficient CT imaging technology. The results show that the in-seam wave is sensitive to fault structure and the detection accuracy is high. The amplitude attenuation coefficient imaging method has high precision. The in-seam wave of Yangcheng coal mine is well developed, which is suitable for in-seam wave technology.
