Application of infrared technique to probe the geological structure is an effective way to prevent serious accident in drift. According to the principle of infrared radiation, the correlation between the changes of rock density and radiation intensity of binding rock in drift affected by geological structure is analyzed. The theory, method and feasibility of infrared probe are put forward. Results of application show that the infrared probe not only could analyze and predict easily and objectively the geological changing trend of the binding rock in drift, but also could detect the cause of gas outburst in the abnormal section of the drift. All these would provide effective measures to prevent the accident.
