| 摘 要： | 根据矿岩在溜井内产生摩擦阻力的不同，矿岩对溜井底部静压力可分为3种状态。其中对第三种静压力状态进行试验和理论分析，得出其计算公式，确定此种应力状态各力的大小，是从力学角度揭开矿岩流动规律的关键。

| Abstract: | Within the ore pass,rock & ore cause different frictional forces that can be divided into 3 type of static pressure and stress.Through testing and theoretical analysis,the calculating formula for No 3 type has been obtained.From the point of view of mechanics,the determining of value of individual sub-forces under condition of No 3 type is essential and dominant for understanding the regularity of rock & ore moving. |

| Keywords: | pressure and stress at bottom of ore-pass trend of movement displacement |
