| 摘 要： | 本文研究煤矸石倾倒过程中的运动特征对矸石山非均质性特征的影响。分析表明,当煤矸石密度相同时,煤矸石在坡面上的运动位移与矸石山高度、初始速度、粒径、球度和磨圆度成正比,这就使煤矸石随矸石山高度的变化粒径分布不均匀,进而造成了矸石山的非均质性。

| Abstract: | This paper studied the effects of the movement characteristics of coal gangue during dumping on the non-uniformity. Analysis showed that, when the density of the gangue is the same, the displacement of gangue movement on the slope is proportional with the waste dump height, initial velocity, particle size, roundness and sphericity, which makes the particle size uneven distribution with the change of waste dump height, thus resulted in the non-uniformity of the waste dump. |
