the aeolian sand-box type filling technology is proposed to solve the problem of filling materials in desertification mining area of Xinjiang
and the lateral constraint control mechanism of aeolian sandbox type filling body is explored by using PFC3D-FLAC3D software. The main conclusions are as follows:(1) When the vibration load is applied to the cage
the aeolian sand compaction of the cube-box type is 2.78 times of the cylinder-box type at 3 s;(2) With the increase of cage size
the wind aeolian sand compaction amount of cylindrical net box is decreasing
and the volume of aeolian sand compaction of 5 cm cage is 12.87 times of 6 cm cage;(3) With the increase of net box strength
the compaction amount of aeolian sand in different types of net boxes is reduced to different degrees
and the reduction of aeolian sand compaction in 5 cm cylinder-box is 30%when the vibration load is 3 s.
