[Objective] The influences of Shenfu coal mining subsidence on the movement of aeolian sand were studies to provide scientific basis and guidance for the controlling of wind erosion and recovery of vegetation. [Methods] Based on local field observation in a typical sand dune

this paper studied the impacts of sand dune position and the surface damage ratio on the thickness of aeolian deposit. [Results] The results showed that the thinkness of aeolian deposits on the ground that had undergone one year of subsidence and two year of subsidence were -28.2 cm and -45.6 cm

respectively; while the reference sand dune was -2.8 cm. The overall probabilities of wind erosion of the above three dunes were >60%

>90%

and<10%

respectively. Surface accumulation occurred more intensely on the surface with a higher damage ratio. The movement of wind-blown sand gradually shifted from accumulation or filling to wind erosion as the surface damage ratio decreased. The relation between the thickness of aeolian deposit(Q) and the surface damage ratio(V) can be described by a polynomial function. [Conclusion] It was concluded that the coal mining-induced subsidence significantly promoted the movement of aeolian sand and changed the thickness of aeolian deposit locally

and it may reactivate fixed or semi-fixed dunes.
