5 Benefits of Automated Mining

Mining businesses the world over are quickly adopting the latest innovations in the world of automated mining technology in order to modernize their operations. For example, in Rio Tinto, Australia, four iron mines make use of 73 driverless trucks in order to mobilize the minerals all 24 hours of the day. Employees supervise the vehicles from 1.200Kilometers away, at the Rio Tinto control center located in Perth.

On the other hand, almost 14.000 Kilometers west, Boliden, a Swedish mining business, is working with the Ericsson mobile phone company in order to build an autonomous gold mine. The 5G network that Ericsson installed on site allows the mine’s ventilation system to save up to 18 megawatts in its yearly use of energy, with represents a 54% improvement in efficiency.

In the United States, mining company Barrick Gold Corporation joined Cisco Systems in order to integrate Wi-Fi sensors to the mines near Elko, Nevada, in order to track production in each mining project. Barrick is making use of this and other automated technologies to reach its goal of diminishing the costs of production for each ounce of gold to 700USD.

Finally, in Africa, mining companies Randgold Resources and AngloGold Ashanti make use of robotic chargers located 800meters under the project’s surface, alongside Kibali Mine, in order to boost production and improve worker safety conditions.

Benefits of automated mining

Automated technologies offer certain benefits that simply cannot be overlooked. Companies that make use of automated mining technologies will notice an immediate, significate increase when it comes to production – as well as a less expenses. Some companies have seen production improve between 15% and 20% after adopting new technology.

The industry will also benefit from a noticeable increase in safety. Through the use of automated equipment that can be used in dangerous, remote areas, mining companies can send less workers underground, thus enjoying increased production while diminishing the risk to the life of employees. For example, after implementing automated technologies in several of its African mines, Randgold Resources saw an improvement of 29% when it comes to quarterly reports of injuries.

It is expected for this rapidly-changing scene to provide substantial value to the mining sector and its stakeholders. Reports suggest that the combination of increased production and safety alongside the diminished expenses can make the automated mining market grow almost 50% in the next six years, reaching 3.290 million dollars come 2023.

José Manuel Mustafá: Uso del hierro en la historia de la arquitectura

El hierro es un metal de transición que abunda en la corteza terrestre y que se encuentra de manera presente en la naturaleza, siendo el segundo más abundante después del aluminio. Este contiene propiedades magnéticas siendo uno de los elementos más utilizados en la industria de la construcción.

Este elemento fue uno de los más utilizados en la arquitectura mundial desde la antigua Grecia, pero el uso de este  tomó mayor fuerza y renombre durante el siglo XIX, donde estuvo el auge de la Revolución Industrial y la nueva era de la construcción moderna.

Para el año de 1836 aparece el perfil “doble T” el cual reemplaza a la madera revolucionando la industria de la construcción por la fabricación de piezas en serie, que consistía en la realización de piezas para alcanzar un producto final.

Entre las obras más significativas que se realizaron durante ese siglo está:

  • El Palacio de Cristal: Construido por el arquitecto Joseph Paxton, fue construido en Londres en el año 1851 y representa una nueva estructura realizada mediante los procesos de prefabricación de armado y desarmado. La estructura tiene 600 metros de largo conformados por naves y bóvedas, además su concepto predomina el vidrio como elemento predominante.
  • Torre Eiffel: Es una de las estructuras de hierro más imponentes a nivel mundial, construido por el francés Gustave Eiffel en el año 1889. Esta estructura se encuentra constituida por más de 18 mil piezas de hierro alcanzando una altura de 305 metros. La misma comenzó a construirse a principio de 1887 y terminado el 15 de abril de 1889.

  • El puente de María Pía y el viaducto de Garabit: Fue realizado por el ingeniero León Boyer, el cual deseaba realizar una variante en el trazado en un tramo de la línea ferroviaria Marvejols-Neussargues de Francia, donde terminaron construyendo un viaducto de 166 metros, siendo una estructura imponente.
  • Museo Universitario del Chopo: Esta estructura fue realizada por la empresa metalúrgica Guttehoffnungshütte de Alemania para su presentación en la Exposición de Instalación y Arte Industrial de Düsseldorf, el cual fue posteriormente trasladado a México donde es utilizado actualmente como un museo de arte.

Hazards When Manipulating Metals

Working in the steel industry is an extremely complex chore; hence, it demands a great professionalism and, above all, lots of mindfulness and follow-up of safety standards, inasmuch as, there are many hazards to which you can be exposed. For this reason, today we want to introduce you some of the most commonly hazards in this work area:

Welding

Welding is one of the most common activities when working with metals,  workers are exposed to toxicity and fever due to metal vapors; this depends on the composition of the material used, such as, electrodes, nickel rods or plasma. To minimize these hazards, it is necessary to have good ventilation in general also the use of personal protective equipment when necessary is recommended.

Noise and vibration

The casting and cleaning operations are the ones that register higher noise levels when working in a foundry, thus being even higher in the mechanized foundries than in the manual ones. Even, for those who work in small workshops, they also may notice that they are exposed to these types of elements. In order to minimize the risks of being affected by these, personal protective equipment should be employed and even though working on sound-deadening surfaces.

Hand-Arm Vibration Syndrome (HAVS)

Using portable vibrating tools can cause Raynaud’s phenomenon or hand-arm vibration syndrome (HAVS). The frequency of occurrence of critical vibration for this problem is between 2000 and 3000 revolutions per minute and, in the range of 40 to 125 Hz. This disorder can be associated with carpal tunnel syndrome and degenerative changes in the joints.

In order to reduce the vibration transmitted to the hands of the workers, it is recommended to use designed tools to minimize the harmful ranges of frequency and amplitude, and moreover to wear overlapped gloves or an insulator and, also reducing the time exposure to this type of tools based on changes regarding to working operations, tools and resting periods.
