本文介绍爱尔兰金属公司提那(Tynagh)露天矿的设计、采准、采矿方法、品级控制等情况。该矿年产矿石70万吨。露天矿设计提那露天矿采矿场长730米,宽213米,最终开采深度将达103米。露天矿将开采所有次生矿带和其下部的100万吨原生矿。次生矿带的形状与露天采矿场轮廓相似,因此剥岩量不多。剥离主要是在次生矿带稍风化岩石中进行。露天采矿场南部边坡断层带附近的岩石也将剥离掉。根据岩石种类和结构,设计的边坡角为45°—60°。露天矿边帮围岩有泥质石灰岩、脉
This article describes the design, acquisition, mining methods, quality control, etc. of the Tynagh open pit mine in Ireland. The mine produces 700,000 tons of ore annually. Open Pit Design Tianya open pit mining 730 meters long, 213 meters wide, the final mining depth will reach 103 meters. The open pit will mine all secondary ore blocks and the 1 million tons of primary ore below it. The shape of the secondary ore zone is similar to that of the opencast mine, so the amount of stripping is small. Stripping is mainly carried out in slightly weathered rocks in secondary ore zones. Rocks near the southern slope of the open pit will also be peeled off. Depending on rock type and structure, the designed slope angle is 45 ° -60 °. Open-pit mine side of the rock surrounded by muddy limestone, veins
