“…Las empresas mineras reconocen que estos peligros, además de amenazar la seguridad de sus trabajadores, disminuyen su índice de producción. Aunque el desarrollo de sistemas automatizados inició desde los años setenta, sus frutos se consolidaron hasta el presente siglo (Ralston et al, 2014).…”

<p>El auge minero en determinados periodos históricos se debe a la incidencia de varios factores, como son el precio de los metales, el desarrollo de la tecnología, y las<br />políticas económicas y ambientales. El presente artículo reseña los principales periodos del desarrollo de la minería en México y profundiza en el más reciente: la aplicación de la automatización. La mayoría de los análisis sociales sobre la minería se enfocan en el concepto de neoextractivismo y hacen énfasis en las políticas económicas y los precios. La aportación de este estudio es sobre los datos de la revolución en las fuerzas productivas del sector minero, aspecto que puede ser igual de importante que los precios de los metales y la política económica en el sector para entender el contexto actual</p>

“…This has been achieved thanks to the miniaturization of electronics. Nowadays, many mine process machines are now fitted with sensors to measure variables such as temperature, vibrations, mechanical stresses, pressure, etc., in order to establish a control panel that will indicate, to some extent, how the machine is working [4][5][6][7].…”

One of the most widely used electro-mechanical systems in large-scale mining is the electric motor. This device is employed in practically every phase of production. For this reason, it needs to be inspected regularly to maintain maximum operability, thus avoiding unplanned stoppages. In order to identify potential faults, regular check-ups are performed to measure the internal parameters of the components, especially the brushes and brush-holders. Both components must be properly aligned and calibrated to avoid electric arcs to the internal insulation of the motor. Although there is an increasing effort to improve inspection tasks, most inspection procedures are manual, leading to unnecessary costs in inspection time, errors in data entry, and, in extreme cases, measurement errors. This research presents the design, development, and assessment of an integrated measurement prototype for measuring spring tension and other key parameters in brush-holders used in electric motors. It aims to provide the mining industry with a new, fully automatic inspection system that will facilitate maintenance and checking. Our development research was carried out specifically on the brush system of a SAG grinding mill motor. These machines commonly use SIEMENS motors; however, the instrument can be easily adapted to any motor by simply changing the physical dimensions of the prototype.

“…For absolute localisation, the absence in the underground of a pervasive positioning infrastructure such as GPS has led to the use of alternative technologies, in particular distributed sensor networks. For applications also requiring high accuracy, inertial navigation systems have been successfully applied by Australia's CSIRO to machine guidance of both longwall and continuous miner applications (Ralston et al 2014). Nevertheless, even high-end inertial systems are prone to drift with regard to the position estimate accuracy over time, and an external reference sensor is therefore required to place a bound on this source of error by correcting the inertial estimate on a periodic basis.…”

A novel radar-based system for longwall coal mine machine localisation is described. The system, based on a radar-ranging sensor and designed to localise mining equipment with respect to the mine tunnel gate road infrastructure, is developed and trialled in an underground coal mine. The challenges of reliable sensing in the mine environment are considered, and the use of a radar sensor for localisation is justified. The difficulties of achieving reliable positioning using only the radar sensor are examined. Several probabilistic data processing techniques are explored in order to estimate two key localisation parameters from a single radar signal, namely along-track position and across-track position, with respect to the gate road structures. For the case of across-track position, a conventional Kalman filter approach is sufficient to achieve a reliable estimate. However for along-track position estimation, specific infrastructure elements on the gate road rib-wall must be identified by a tracking algorithm. Due to complexities associated with this data processing problem, a novel visual analytics approach was explored in a 3D interactive display to facilitate identification of significant features for use in a classifier algorithm. Based on the classifier output, identified elements are used as location waypoints to provide a robust and accurate mining equipment localisation estimate.
