摘要
从散体力学的角度,分析了矿石块度大小、粗颗粒矿石含量对抗剪强度的影响。通过室内模拟试验,深入研究了放矿过程中崩落矿石块度对放矿规律及放出体大小的影响,得出了矿石块度组成是影响放出体形状和大小的重要因素的结论,对现场生产具有指导意义。
The effects of ore fragmentation and coarse particle content on shear strength are analyzed from the angle of mechanics of granular media.On the basis of simulation tests in the laboratory,a thorough study is carried out on the effect of caved ore fragmentation in ore drawing law and drawn-out body of ore during ore drawing.It is concluded that ore fragmentation is an important factor that affects shape and size of the drawn-out body of ore,which gives a reference to the practical production.
