Belt conveyors are widely used in the mining industry, both in open-cast and underground mines. They offer advantages such as rapid transport of blasted heaps from the depths to the surface, and many others. However, their use in underground mines has a number of drawbacks. Let’s explore some of them. Fire hazards Underground conveyor belts, […]

According to Ammar Ali, Ex Engineer Intern at Freeport Indonesia with expertise in Mine Ventilation DMLZ-PB4, the VOD concept is one of the energy-saving principles in underground mine ventilation systems (can be applied to all commodities). VOD is the ability to provide air intake into underground mines to areas that need it, in other words […]

The final pit design in open-pit mining is a complex optimization process influenced by geological, economic, geotechnical, operational, and environmental factors. These elements collectively determine the pit’s boundaries, slope stability, profitability, and long-term viability. Below are the key determinants: Geological and resource characteristics Deposit geometry and mineralization: the ore body’s shape, depth, grade distribution, and […]

Simply put, pushbacks are a sequence of controllable stages that can be exploited with the mining equipment currently in use and that can satisfy operational and geotechnical mining constraints. In the design and optimisation of open pit mines, pushbacks are extremely important. Since the underlying set of pushbacks serves as the basis for production scheduling, […]

In open-pit mining, the inter-ramp angle refers to the angle of the slope between two consecutive ramps or haul roads, encompassing multiple benches.  The overall slope angle (OSA) is the angle measured from the toe of the pit wall to the crest of the highest point, encompassing all benches, ramps, and haul roads within the open pit […]

Botswana’s main diamond company has paused production at some of its mines, citing a prolonged downturn in global demand. Debswana, a joint venture between the government and global mining giant De Beers, saw its sales revenue drop by almost 50% last year. Botswana is the world’s largest producer of diamonds by value. The industry accounts […]
