前苏联的各类露天矿受原有的露天开采统一安全规程的限制，边帮角一般比计算的稳定边帮角小8°～10°以上，充分利用边帮稳定性的潜力可获得巨大的经济、社会和生态的效益。简要地介绍了按破坏机理对组成边帮岩体所做的分级和在不同级别的岩体中完善非工作帮结构的可能方案。举例说明了俄罗斯一些露天矿改造边帮取得成功的经验。强调了研究制造专用钻机的迫切性。
Various types of open-pit mines in the former Soviet Union are subject to the conventional safety regulations for open-pit mining. The edge angle is generally smaller than the calculated stable edge angle by more than 8 ° ~ 10 °, and the potential for edge stability can be fully utilized. Economic, social and ecological benefits. This paper briefly introduces the classification of rock mass composing the edge rock mass according to the failure mechanism and the possible solutions of perfecting the non-working rock structure in rock mass of different grades. An example is given of the successful experience of the transformation of some open-pit mines in Russia. Stressed the urgency of researching and manufacturing special rigs.
