摘要
Based on the theory of engineering geology, the authors analyzed the data of the specific geological phenomenon revealed by topography, strata characteristics, costeaning and adit exploration engineering, showing that a huge ancient slide exists in Wujiagou goldmine. The analysis of its scale and characteristics indicates that the surface ore belt of Wujiagou goldmine is located on the ancient slide as talus slide. According to the dip gradient of the slide and occurrence of slide surface, the planar location of undamaged goldmine is located at 80~120 m to the north of surface ore.
