在矿山开采过程中，破碎带、软弱夹层等地质构造以及隐患空区的存在严重影响矿山的生产安全。开采前对工作面前方的地质条件进行超前预报，并及时采取有效的应对措施，对于矿山安全、经济且高效开采具有重要意义。为了探明某金铜矿深部矿房塌陷后涉及多中段的复杂空区位置和形状，在现场勘查的基础上，采用TRT6000系统分多中段多测点对需探测区域进行了不同方位的探测，结合钻探结果对预报结果进行详细分析与验证，并建立了反映空区形态的三维模型。结果显示TRT6000系统预报结果与钻探结果基本吻合，表明应用TRT在矿山井下开展超前预报具有可行性。建立的三维模型更加直观地揭示了空区及破碎带等问题区域可能出露的位置，为TRT结果解译的可视化提供了参考。

Geological disasters such as collapse of tunnel roof or wall and water inrush seriously threaten the life and property safety in the underground mine.It is particularly important to predict the geological conditions ahead before excavation.Based on advanced prediction，the discontinuous structures such as broken zones，weak interlayers and goafs can be found in time. Then， the geological disasters can be greatly reduced under effective measures，which is of great significance to the safe，economic and efficient mining of mines.It is discovered that the No.5 stope in the deep granite porphyry area of an underground gold-copper mine collapsed with a suspected goaf，which caused great potential safety hazards to subsequent production.Tunnel Reflection Tomography （TRT） technology，as a medium and long-distance advanced prediction technology，has the advantages of low-loss materials，convenient operation，safety and stability，and it is currently being gradually promoted and used in mines.In this paper，the TRT6000 system was applied to complex empty areas detection of this gold-copper mine，including 6 detection points distributed in 3 middle sections.Furthermore，a space three-dimensional model was established to make up for the lack of demonstration and observation of the imaging results of the TRT system.By comparing the results obtained from the interpretation of the TRT with the drilling results available，it can be found that the area covered by the borehole is basically consistent with the results of the advanced prediction of the TRT.The established three-dimensional space model intuitively reflects the distribution range of problem area such as broken zone and mined-out area，so that mine producers can have a clearer understanding of the specific situation.The TRT prediction results are basically consistent with the detection drilling results，which proves the feasibility of TRT advanced geological prediction technology in underground mines.The three-dimensional model is innovatively established to visually demonstrate and observe the TRT interpretation results，and achieved a good result.It provides ideas and directions for the visualization of TRT results interpretation.
