The thick sandstone aquifer of the Cretaceous Yijun formation is rich in water and poor in predictability. Under this circumstance, the issue of the main inclined shaft of the mine in western China has been studied. Then, the comprehensive geophysical method is used in the field for advanced exploration and prediction. Based on the mine transient electromagnetic method and direct current resistivity method, the comprehensive advanced detection is carried out. Furthermore, the low resistance area in front is determined, the geological anomaly position and characteristics in front of the head are judged, and the water rich area of the detection is qualitatively evaluated, which provides support for the formulation of production technology scheme. The driving construction verification shows that the result of comprehensive geophysical exploration is basically consistent with the actual one of the shaft, and the detection accuracy of the relatively rich water area reaches over 80% which demonstrates that the comprehensive geophysical exploration method can be effectively applied into the construction of inclined shaft driving.
