【摘要】：针对大高差溜槽倾角不能按照常规的单因素方法确定的问题,采用理论分析与实验研究相结合的方法,以废弃露天矿坑回填为研究背景,考虑物料含水体积分数和粉岩体积分数多种因素,研究溜槽倾角的确定方法.结果表明:在含水体积分数达到最大吸水率范围内,含水体积分数ρ与溜槽倾角α的关系是趋于直线上升的,并确定拟合函数表达式;粉岩体积分数与倾角的关系曲线是趋于对数函数关系,并确定拟合函数表达式;当粉岩体积分数ω超过约58%之后,溜槽倾角基本不再增大,趋于33°,提出溜槽倾角的确定公式.
[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 伪 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 掳. The formula for determining the chute inclination angle is put forward.
