中文摘要：

为实现金属矿山井下复杂环境的地质超前预报,通过分析与铁路隧道中超前探测的差异,建立基于TRT技术的井下超前预报基本程序,运用TRT6000系统,开展井下地质超前探测和预报。以铜坑矿为例,现场采用多点激发和多点接收,实现了三维空间反射层析成像,获得了较为全面的空间波场信息。根据该矿山井下6个有效探测点的数据分析和解译,获得了目标巷道前方有效距离30~150 m的三维成像结果,直观和量化地反映了工作面前方的破碎带、采场和塌落区的位置和范围,并将TRT探测结果 与工程实际情况进行比较。最后分析TRT技术在地下矿山应用中存在的问题和注意事项。

英文摘要：

For the purpose of making advanced geology predication under complex underground surroundings in metal mine, a basic procedure for advanced prediction in mine underground was established after analyzing differences between railway tunnel and underground mine. A TRT6000 system was used for advanced detection and prediction in an underground metal mine. In Tongkeng mine, taken as an exam- ple, multiple-point excitation and receivtion were used for reflection tomography in three-dimensional space, and full-scale space wave field information was obtained. According to analysis and interpretion of data fiom 6 effective detection points, a three-dimensional geology image of 30 - 150 m in front of tunnel face was obtained. It reflected the crushed zone, stope and caving area visually and quantitatively. A comparison was made between results and practical engineering. Finally, problems in the application and matters worthy of note were discussed.
