当前,露天开采中一个很重要的问题,是如何克服开采深度对生产经济指标的不利影响。一般来说,产生这种情况有两个主要因素:自然因素和生产因素,后者又可分为工艺技术和社会环境两个方面。自然因素主要是指矿岩的物理机械性及其埋藏条件。生产因素中的工艺技术主要是指运输距 At present, a very important issue in open pit mining is how to overcome the adverse impact of the mining depth on the indicators of production economy. In general, there are two main factors that cause this situation: natural factors and production factors, the latter can be divided into two aspects of process technology and social environment. Natural factors mainly refers to the physical and mechanical properties of ore rock and its burial conditions. The production technology in the main means of transport distance
