REAL-TIME AIR QUALITY MONITORING: CHALLENGES AND CONSIDERATIONS

World Mining Congress
The ability to continuously monitor the air quality within a mine has become instrumental in becoming a low cost producer. The many considerations involved in monitoring air quality include sensor type, hardware placement, as well as data storage medium. BESTECH has had the opportunity to gain insight into these air quality monitoring considerations through deployments of NRG1-ECOTM, a minewide energy consumption optimization system. This paper explores the particular challenges overcome through these installations, and provides a set of guidelines for mines that want to maximize data capture while minimizing costs. It provides a view of additional benefits of air quality monitoring, such as ventilation control, reporting and trending.

Summary: The term “cost” is too small when describing the destructive power of safety incidents for mining companies. Breaches in employee or environmental safety are felt way beyond the bottom-line: human life can be taken; ecosystems tarnished; the ire of peoples, media and government inflamed; significant halting of production; and high levels of legal and financial challenges. According to a recent survey of Mining executives, “ensuring workforce safety” was the most important issues identified...

Summary: Bowtie analysis has recently emerged as a technique of choice that can be used when looking specifically at major hazards in the mining industry. A Bowtie diagram is a graphical means of assessment that focuses on identifying all the specific causes and consequences of major events, from which all the “pre-event” and “post-event” control measures can be identified. From this critical control measures can be identified and monitoring/assurance systems can be established.

Summary: In these times of increasing costs and diminished returns, energy consumption is one source of savings that remains relatively untapped in the mining sector. Typically, 15% to 40% of operational costs can be attributed to energy in mining operations. This “process variable” is a complex, multi-faceted variable that involves government regulations, societal pressures, cost and competitiveness. A mining company able to successfully embrace an energy efficiency program is more often than not a...

Summary: Mining dilution is one of the most important factors affecting the economy of mining projects. Ore losses and dilution are present at all stages of mining and while several models can investigate the influence of dilution it is its quantification that poses the most serious challenge (Pakalnis et al., 1995). This paper introduces a methodology to quantify dilution factor in open pit mines. The proposed approach makes use of general mining software available in most mining companies. Therefore...

Summary: Uranium mining remains controversial in many parts of the world, especially in a post-Fukushima context, and often in areas with significant uranium resources. Although nuclear proponents point to the relatively low carbon intensity of nuclear power compared to fossil fuels, opponents argue that this will be eroded in the future as ore grades decline and energy and greenhouse gas emissions (GGEs) intensity increases as a result. Invariably both sides fail to make use of the increasingly...

The major use of pillars is in room-and-pillar type mining. Pillars are critical structures in the production levels of block cave mines. With most mines leaning towards the use of block caving for ore extraction today, pillar design has become even more important. Empirical pillar design is popular. The use of numerical modeling is...

Summary: Arsenical bearing deposits are posing an increasing challenge for the mining industry. In particular, mineral processing of arsenical sulfidic ores for base and precious metals recovery tend to produce problematic arsenical tailings. This arsenic being present as sulphide or oxide, tends to dissolve, contaminating surface and underground waters. To meet the environmental regulations, it is often required to stabilize the arsenic in a more insoluble form. Nichromet has developed a new patented...

Summary: Coal consumption has increased globally by 57% over the last ten years. Underground mining typically provides coal of the highest calorific value and accounts for the greatest proportion of production. Despite a negative environmental image and indeed impact, this industry appears likely to thrive on the global scale for many years to come. Such mining consumes large amounts of electricity with implications for carbon dioxide emission at power plants and emits substantial quantities of the...
