Coal mining under rivers can be improved by determining the height of waterflowing fractured zones. By analyzing the composition and structure of rock strata, researchers found that the waterflowing fractured zone after slice mining is around 52 meters high. This information helps in setting limits for coal mining and retaining waterproof coal pillars.
