Introduction: How to solve the contradiction between coal mining and soil water conservation is a key scientific problem realize ecological environment protection high-quality development in middle reaches of Yellow River. Methods: Using FLAC 3D numerical simulation experiment method, influence loess slope surface shape seam overburden structure coupling on movement deformation studied. Results: Under any shape, average subsidence coefficient ( q ) increases with increase sand layer after subsidence. When less than 0.71, rapidly, an more 2.86%, when greater tends be stable. decreases sand-mud ratio. characteristics natural are or equal 5°, convex largest, four types ranked as follows: > straight ≈ composite concave slope; structural overlying strata order slope. With slope, first then increases, inflection point 15°. The law morphology horizontal similar that surface. Discussion: results can provide basis for area northern Shaanxi River Basin China.
