It is complex that geological structure in the Chishui survey area of Zhangping City, the nappe fracture development in northern and central, It stored good coal strata under Nappe. It is a breakthrough for looking deep coal. Between the layer slippage fracture developments, it is expected to find more shallow coal resources under the new stratum. But granitoids make great harm to coal strata,  it completely lost economic value. Through research the geological characteristics, using the theory of nappe, combined with deep drilling verification, the authors put forward the direction of the deep looking for coal.
