Controlling dust in underground mines is one of the greatest ongoing challenges for mine operators in South Africa, particularly in coal mines. Oftentimes, the focus on dust control at mine sites is on the dust that is generated above the ground as it is more visible and prominent. However, fugitive dust from underground mining activities should always be of key concern.
Dust is an inevitable part of materials mining. It’s an unfortunate truth that something so small can cause far-reaching health, safety and environmental impacts. In this article, we’ll take a look at the different types of dust generated by mining operations, specifically PM10 dust. We’ll also explore the long term consequences of breathing in PM10 dust, relevant legislation in regards to exposure limits, and how mines can implement highly effective control measures for reducing worker and
Dust control needs to be treated as a site-wide issue in open-pit mines. This is because there so many dust generation points to contend with all at once, from haul roads to tipping points to blasting activity. Consequently, innovative solutions are required for each and every stage of operation.
One of the biggest perpetual problems faced by underground mining operations is excessive dust levels. Working in confined spaces with limited atmosphere and with so much activity going on (blasting, drilling, emissions from overburdened vehicles hauling over dusty roads), maintaining adequate clean air supply is critical.
Dust-A-Side’s high pressure mist systems are just one of our innovative solutions designed to suppress dust in a wide range of applications. These systems produce a high concentration of 10-micron droplets in a mist that can be directed at areas that produce a high concentration of airborne dust.
Prevention is better than cure, because there simply is no cure The world breathed a collective sigh of relief twenty years ago when the dreaded black lung disease was thought to have been eradicated once and for all. However, this occupational lung disease – known more formally as coal workers’ pneumoconiosis – is back, and steps must be taken immediately to prevent its spread.
