采矿工作者往往乐道于提高最终边坡角的重大意义,乃至乐道于最终边坡角提病一度时所得到的巨大经济效益,然而却总是难于提高。相反,由t边坡事故的出现所带来的巨大危害,却得到了降低最终边坡角啦结论。这里认为t遵循传统的采矿坑结构的设计原理和方法,欲提高最终边坡角是困难的。这是因为若按岩石的稳定性能,∥所谓的合理的边坡角来
Mining workers often feel the great significance of raising the final slope angle and even the great economic benefits that the jobless brings when the ultimate slope angle becomes acute. However, it is always difficult to improve. On the contrary, the tremendous damage caused by the occurrence of the t-slope accident has led to the conclusion that the final slope angle should be reduced. Here, we believe that it is difficult to follow the design principles and methods of the traditional mining pit structure in order to improve the final slope angle. This is because if the rock stability, ∥ so-called reasonable slope angle
