1 Introduction The problem of equipment selection in a surface mine is complex. Many features, restrictions and criteria need to be considered (Naoum and Haidar 2000). The model must reflect the important constraints of the mining operations to a level that is
The R2900G underground loader is designed for high production, low cost-per-ton loading and tramming in underground mining applications. Compact design with agile performance, rugged construction and simplified maintenance ensures excellent productivity, long life and low operating costs. Engineered for performance, designed for comfort, built ...
Equipment selection for open-pit mines is a major decision, which in turn, impacts greatly on the economic viability of an operation .Models for equipment selection and evaluation described by Celebi  were aimed at selection of the equipment
Stationary equipment at a surface mine typically performs hauling, processing, and other service functions. Structures provide offices, storage, and maintenance spaces. The following stationary equipment and structures are common to most surface mining operations: Conveyor systems. Feeders, bins, and hoppers. Crushers and screens.
We are currently developing above 120 kilometres per year, and mining over 10 million tonnes on our multi-million-dollar fleet of underground mining equipment. With new projects forecasted, this will see Barminco and AUMS grow to over 5,100 employees in 2021, across 25 projects in seven countries.

Ventilation in underground mines and tunnels. In closed environments like mines and tunnels, ventilation is crucial to maintain sufficient quantities of oxygen and keep air free of dust, toxic gases and vapours. We have produced guidance that outlines the ventilation needed for different types of mining and tunnelling operations.
