三维地震勘探在复杂矿山勘查中的应用

Application of 3D seismic exploration in complex mine exploration

现阶段贵州复杂矿区三维地震勘探工作进行较少,因地形复杂,且变化剧烈,施工及资料处理难度较大,针对此种情况,在施工采用多种措施,获得较高质量的野外资料,处理中利用Seismic studio和ToModel两种层析反演静校正技术进行比较,利用速度分析与优势频段剩余静校正迭代方法进行剩余静校正,获得了质量较高的时间剖面,较好的解决了贵州复杂地区矿山三维地震勘探应用问题。

At present,there is less 3D seismic exploration work in Guizhou complex mining area.Due to the complex terrain and dramatic changes,the construction and data processing are difficult.In view of this situation,a variety of measures are adopted in the construction to obtain high-quality field data.In the processing,two kinds of tomographic inversion static correction technologies,seismic studio and TOMODEL,are used for comparison,and velocity analysis and dominant band residual are used The iterative method of residual static correction is used to carry out residual static correction,and a high quality time profile is obtained,which solves the application problem of mine 3D seismic exploration in Guizhou complex area.
