| 中文摘要: |
| 微动HVSR（Horizontal to Vertical Spectral Ratio）谱比法是分辨第四系覆盖层、松散层、尾矿堆积物厚度较为有效的方法，且工作方便快捷，利于施工。柳州市融水县多个矿区急需查明矿区内尾矿堆场储量，为更加清楚地获得矿区内尾矿堆场储量情况，本文开展微动HVSR谱比法测量，结合矿区相关资料，划分了尾矿堆积物与基岩的分界线并分析其起伏情况，对尾矿堆积场厚度进行推断，并估算其储量。通过多个钻孔验证，钻孔揭露的尾矿堆积物厚度与物探异常推断的成果基本一致，取得了比较良好的物探勘查效果，为下一步尾矿库的处理及下一步工作提供了物探依据，该法可为划分尾矿库堆积物厚度工作提供参考。 |
| 英文摘要: |
| The micro-seismic of Horizontal to Vertical Spectral Ratio （HVSR） method is an effective method for distinguishing the thickness of Quaternary cover layers， loose layers， and tailings deposits. In order to obtain a clearer understanding of the tailing's storage capacity in Rongshui County， Liuzhou City， the HVSR method was carried out in the mining area. The data of HVSR method is calibrated by borehole results from the mining area， and the depth of boundary between tailings deposits and bedrock was determined. Then， the 3-D structure is derived from the interpolation of the result by scattered measurement point， and the tailing’s storage capacity is evaluated. The result is verified by multiple drilling works， which implicit that the thickness of tailings deposits evaluated by HVSR method have a high accuracy. This work demonstrates that the micro motion HVSR method has a good performance on determine the thickness of tailings deposits. |
