露天矿非工作帮的边坡角是根据台阶参数确定的。如改变这些参数和在某些条件下采用提高台阶稳定性的专门措施,就可使总的边坡角在一定范围内加大,但是该角不许超过用计算法确定的极限值。对比生产露天矿边坡角的设计值α_п与最大计算值α_(пP)表明:大多数露天矿的设计边坡角大大低于极限的允许边坡角
Open pit mine slope angle is based on step parameters to determine. If these parameters are changed and special measures are taken to improve the stability of the step under certain conditions, the total slope angle can be increased within a certain range, but the angle must not exceed the limit value determined by the calculation method. Comparing the design value α_п with the maximum calculated value α_ (пP) of the open pit slope angle shows that the design slope angle of most open-pit mines is much lower than the allowable slope angle of the limit
