露天矿开采程序主要由以下几个要素构成:开采台阶、采场降深、工作线布置及推进方式、工作帮。开采程序的确定也就是几个构成要素的选择过程。
开采台阶包括台阶形式和台阶高度的确定。一般台阶形式是水平划分的,特殊时也有倾斜分层。台阶的高度主要取决于采掘设备的挖掘高度、装载方式(上装或平装)和穿爆等因素。当矿体倾角缓、厚度较薄、品级和夹层多时,为减少开采损失,台阶高度不宜过大。
Open pit mining process is mainly composed of the following elements: mining level, mining depth, the layout of the work line and advance, work to help. The determination of the mining program is a selection process of several elements.
The mining stage includes the determination of the form of the steps and the height of the steps. The general level of the level of the level of the division, the special time also has the tilt stratification. The step height depends on the height of mining mining equipment, loading (upload or Paperback) and blasting etc.. When the dip, thin thickness, grade and sandwich for a long time, in order to reduce mining loss, step height should not be too large. |
