A new concept, equivalent economic stripping ratio, is put forward, which not only considers both main factors——the mining rate and the safety, but also reflects a correct principle, “priority of surface min.
在此基础上，提出了当量经济剥采比的新概念，既考虑了回采率和安全性两个主要因素，又体现了“露天优先”的正确原则。
The concept of the steep end-slope mining stripping ration was put forward.
运用露天采矿学的基本原理,提出了端帮靠帮开采的基本方法、实现形式、基本条件以及靠帮开采的意义,给出了靠帮开采剥采比的概念;在单一煤层和复合煤层情况下,推导出了2种端帮靠帮开采方式的靠帮开采剥采比计算公式,建立了不同煤层厚度和覆盖物厚度对靠帮开采剥采比影响趋势预测的数学模型和图示方法。
In the surface mine,the length of working bench is directly related with production stripping ratio.
露天矿工作线的长度不仅与生产剥采比发生直接关系,而且还影响到露天矿的运距、基建工程量等,进而影响整个露天矿的经济效益,因此,合理确定露天矿工作线的长度非常重要。
For the reason,the new economic reasonable stripping ratio applicable for II mining area of Wengfu Yingping Open-pit Mine was determined to adjust and optimize final mining area of open-pit mine.
随着磷矿市场供求关系的变化,磷矿石销售价格大幅度上涨,矿山企业原来确定的露天境界可根据市场因素进行综合优化,为此重新计算了适合于瓮福磷矿英坪露天矿Ⅱ号坑采区的新的经济合理剥采比,以调整和优化露天开采最终境界。
