After dissolution, the rock mass is generally filled with water or mud, and the resistivity is relatively low. As can be seen from the figure, the strata are divided by overburden and bedrock. There is a low resistance body in the bedrock, 80-120m in the horizontal direction and 15-30m in the vertical direction, with a resistivity range of 40-90 Ω * m, which is inferred to be a karst cave based on geological data. After drilling and verification at 95 meters, karst caves filled with mud-water mixture were found in the range of 23-30 meters deep, which is consistent with the high density detection results.
