大高差溜槽傾角確定方法的改進
[Abstract]:In order to solve the problem that the inclination angle of chute with large height difference can not be determined according to the conventional single factor method, the method of combining theoretical analysis with experimental research is adopted, and the backfill of abandoned open pit is taken as the research background. Considering the water content of materials and the volume fraction of powdery rock, the method of determining the inclination angle of chute is studied. The results show that the relationship between the volume fraction of water and the inclination angle 偽 of chute tends to rise in a straight line when the volume fraction of water cut reaches the maximum water absorption rate, and the expression of fitting function is determined. The relationship curve between powdery rock volume fraction and dip angle tends to logarithmic function, and the expression of fitting function is determined. When the volume fraction of silt exceeds about 58%, the chute inclination angle no longer increases and tends to 33 擄. The formula for determining the chute inclination angle is put forward.
