To know the compression properties of ZKD super-high-water packing material in the specific underground environment,the theoretical model of calculating equivalent mining heights of both the single filling working face and strip filling working faces were deduced from the method of any point subsidence prediction with probability integral method based on surface subsidence values.The compression ratio of ZKD super-high-water packing material in thespecific underground environment was researched according to the filling rates of each working face.The results show that the compression ratio of super-high-water material is about 10% in the specific underground environment.It provides a technical reference to fill with super-high-water material in similar geology and mining condition.
