Design, including open-pit slope angle to help determine a reasonable use of state stripping ratio of not more than economic stripping ratio open-pit mining of the principle of delineation of state, chosen to open up the road motor transport. Trench digging work carried out the calculation of production capacity and to verify the progress of the preparation of a mining plan. Parameters and procedures for the mining, ditch digging capacity, balanced stripping ratio, blasting, mining equipment technology, exclusive territories, implementation schedule for the projects such as mine has done a narrative. ……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………… Key words: Open-pit mining Stripping ratio Blasting Economic indicators 目录 摘 要 I Abstract II 第一章 地质部分 1 1.1 区域及矿区地质概况 1 1.1.1 矿石地质特征 1 1.1.2 水文地质概况 1 第二章 露天开采境界 2 2.1 露天开采境界确定的原则和方法 2 2.2 确定境界所需的技术经济指标 2 2.2.1 经济合理合理剥采比的选定 2 2.2.2 露天矿的最小底宽 2 2.2.3 最终边坡角 3 2.3最终开采深度的确定 3 2.2.4 露天矿开采深度的初步确定 3 2.2.5 露天矿底部标高的调整 7 2.3 露天开采境界的参数 7 2.3.1 露天矿的底部周界 7 2.3.2 露天采场的构成要素 8 2.3.3 境界内的矿岩量及开采年限 8 第三章 矿岩采剥工程 12 3.1 概述 3.2 穿孔工作
