Taking Tengbei No.5 well as an example, this paper introduces the application of underground supine hole to detect and understand formation related parameters and water-richness when coal mining under water. The analysis of the data of the loose layers, the Jurassic strata and roof sandstone exploratory holes provides an important basis for the safety and economic exploitation of the 310 2 and 3 upper 10 2 faces of the Tengbei No.5 well
