Rail haulage once ruled underground mining but lost its dominant position due to the flexibility and investment advantages of truck or conveyor haulage. New locomotive technology makes a strong case for returning to rail—and not just for the largest mines.

Based on the life cycle assessment (LCA) method, this study explores the environmental impact of the railway transportation of ore from the Bayan Obo Mine.

Ore Handling. It is the process of handling ores from stoping face to haulage level. According to the main acting force exerted on the ores and handling equipment in the process, the ore handling is classified into gravitational, mechanical, explosive, and hydraulic handling. The first two types are applied widely.

Posted by Daniel Gleeson on 9th September 2021. Epiroc says it has won a large order for mining equipment and service from Dazhong Mining Co Ltd in China as part of a plan to expand two of its underground iron ore mines in the most "safe and productive manner possible". Dazhong Mining has ordered a variety of rigs for face …

Mines especially open cast iron ore mines, due to its own peculiarities can cause disturbance in ecology, resulting in various pollution problems. The environmental problems are more significant in India, as most of the iron ore mines located on top of hills and in dense forest areas.

These two equipments play a significant role in loading and hauling in mining and processing area. Generally, Andesite stone excavated using an excavator and …

This paper introduces a new microscopic operational-level mining optimisation problem called the Mine Excavator Timetabling (MET) problem, which was moti-vated by real-world research projects with the cooperation of an iron ore mining company in Australia.

This study aimed to develop and assess the feasibility of different machine learning algorithms for predicting ore production in open-pit mines based on a truck-haulage system with the support of the Internet of Things (IoT). Six machine learning algorithms, namely the random forest (RF), support vector machine (SVM), multi-layer …

The Kolomela mine is located 22km from Postmasburg in the Northern Cape province of South Africa. The mine produces direct shipping iron ore.

The production of iron ore for the Sishen-Saldanha Export Project began in 1976 after considerable expan-sion of the pit equipment and facilities. An additional, improved heavy-medium beneficiation plant was also built. The maximum total output of these two plants, which supply lumpy and fine ore for domestic and ex-port markets, is rated as 27 million …

By implementing XMPro iBOS's real-time monitoring and analytics platform, iron ore mining operations can achieve substantial improvements in loading and hauling …

Lizotte [1] affirmed that equipment selection affects economic considerations in open-pit design, particularly showing overburden, waste rock and ore mining costs and cost escalation parameters as a function of plan location and depth. Mining costs are a function of site conditions, operating scale and equipment.

Cost savings presented by new technologies and computational resources that allow companies to modernize mining equipment are offset by increasing equipment complexity, which can lead to higher ...

The open pit mining load and haul system has been a mainstay of the mining industry for many years. While machines have increased in size and scale and automation has become an important …

Traditionally, in open-pit mines, the ore has been predominantly mined by conven-tional mining systems, including shovels and trucks. However, with increasing operating costs associated with hauling rock farther, longer hauling cycle times, increasing diesel prices [3] and environmental and safety commitments, several innovative projects …

Ghaziani et al. (2022) applied simulation and metaheuristic approaches to improve the production rates of loading and haulage operations based on a real-world case study in an open-pit copper mine.

By Our Staff A Chinese mining firm has carried out its first Shipment of Iron Ores from Liberia. China's Baowu Group-backed Bao Chico Resources Liberia Company completed its first shipment of iron ores from the Bong mine area this week. A bulk carrier loaded with 45,000 tonnes of iron ore set sail from the BMC […]

It should be noted that the types of preference functions in the selection process of underground hard rock mining equipment were determined based on expert …

An iron ore mine in South Africa has further leveraged Modular Mining's DISPATCH fleet management system algorithms and OEM interfaces to automate the haul cycle tracking.

The ore rock in the surface mine is usually divided into layers of a certain height, and each layer constitutes a step for stripping and mining. The production …

An underground loading equipment is to scoop up the blasted ore or waste rock in the underground roadway and stopes and unload them to the transportation …

The mining industry faces many difficult challenges, for example, lower ore grades, smaller and deeper deposits, and longer transportation distances. In the past, there have been remarkable innovations in both equipment and the types of mining methods for which it is used, which have resulted in economies of scale. This has led to an increased …

The haulage of ore and waste is an important activity in every underground mining operation. Generally, the haul-age of these materials, represents 20-25% of the total mining costs. However, it is also one of the activities that is least tracked with regards to productivity and costs. But there is a big opportunity to increase productivity and re-duce …

Loading and hauling excavated materials represent a very significant component of the total operating cost of a surface mine. Consequently, incentive to reduce cost in this area remains high. A reduction in the unit cost of loading and hauling has been achieved, on one hand, by applying new and innovative mining equipment and methods, and on ...
