Abstract: Taking a middle section tunnel project of a super-deep metal mine in Yunnan province as anexample, this paper expounds in detail the basic principles , advantages and disadvantages, and opera.tion methods of infrared detection. This paper discusses the practical application of the HS-S310 infraredwater detector in geological prediction of exploration engineering in super-deep metal mines and analyzesthe experimental results and treatment methods of infrared water detection technology under the influenceof several interference factors. The experiment proves that the method is easy to operate and has highprediction accuracy. The water-rich state in front of the tunnel can be displayed by data inversion andthree-dimensional imaging. But this method is easy to be disturbed by construction site conditions. Byusing this infrared water detector to canry out advanced geological prediction, and make advanced predic.tions of the geological conditions ahead of the tunnel can lay a foundation for adopting the new water ex.ploration model of  drilling  geophysical exploration + short exploration”and using multiple forecastingmethods in combination, and plays a guiding role in improving the accuracy , economy and feasibility ofgeological prediction ahead of time.

Key words: infrared water detection, working face, advanced prediction, karst development
