One of the biggest perennial problems faced by underground managers, supervisors, HSE officers and workers themselves is dust suppression. Working in confined spaces with limited atmosphere, and so much activity going on – blasting, drilling, emissions from vehicles hauling overburden over dusty roads, etc – maintaining adequate clean air supply is critical. Whilst effective primary and secondary ventilation systems are of utmost importance in extracting or diluting the mine of contaminants
When those at the helm of a large infrastructure project at one of Australia’s largest ports* required the primary access road to the project treated for dust and erosion, they had no hesitation in selecting Dust-A-Side Australia – the dust suppression specialists – as preferred supplier. Similarly, Dust-A-Side were quick to recommend AquaTarp as the ideal solution. This solvent-free water and surfactant-based emulsion of latex polymer is specifically formulated for easy application onto
Investing in a haul road is a great way to protect your valuable asset and deliver exceptional ROI. However, in both surface and underground mining, badly designed and poorly maintained haul roads, be they permanent, semi-permanent or temporary, can significantly increase costs. Not only do you have to factor in aspects such as increased fuel, tyres and other running costs, plus the repair / replacement of major equipment, but there are also long-term and indirect issues such as lost production
Introducing Dust-A-Side Australia’s High Pressure Mist System, the innovative way to suppress dust in a wide range of applications. The dust suppression system produces a high concentration of 10-micron fog droplets that can be directed at particular nuisance areas that would otherwise produce high amounts of airborne dust. The super-fine water droplets – a mere 10 millionths of a meter in diameter – provide optimum performance for attracting and suppressing PM10 and smaller dust particles.
Nearly 80% of our coal comes from open cut coal mines (compared with 40% globally). There are many issues associated with particulate matter in open cut mines that MUST be addressed. Several mines’ concentration of this matter often exceed the Ambient Air Quality NEPM standard (50 ug/m3 for standard 24-hour average PM10.) Complaints from members of the public about air quality are widespread and in the majority of cases these complaints are based around coal dust. Australia produces
Almost two years since it closed for a $50 million upgrade, the famous Eagle Farm Racecourse in Brisbane was all set for a grand re-opening. There was only one problem, and it was a big one. Over 22 months of intense construction had resulted in huge stockpiles, with the topsoil in danger of running off or causing a massive dust problem. But dust and soil erosion weren’t the biggest problems…the main issue for the Brisbane Racing Club (BRC) was that it was the week before two of the flagship
As well as being a major maintenance and safety factor, poor quality roads are proven to adversely affect fuel economy and total road user costs. In a special study commissioned by Dust-A-Side and conducted by leading tyre manufacturer, Michelin, at their cutting edge mining test centre in Spain, the impact of Dust-A-Side’s Haulroad Management System on the fuel consumption of rigid dump trucks was assessed. The results were quite impressive, however for those familiar with Dust-A-Side’s
Are your existing haul roads costing you a fortune to maintain, and in the back of your mind are you thinking: ‘There must be a better way?’ Do you really consider Total Road User Costs when making important and often costly decisions about investing in the construction, upgrade and on-going maintenance of your haulroads? Dust-A-Side Australia has the perfect solution…our ‘big picture’ Road Maintenance Savings Estimator. Read all about it… Dust-A-Side has several hundred years of combined
Mine haulroads are the backbone of any mining operation; designed and constructed to enable haulage of ore, coal, waste or other commodities from ‘Point A’ to ‘Point B’ in the most efficient manner. It therefore goes without saying that haulroad maintenance is an essential part of optimising mine production and striving for the lowest possible cost-per-tonne. However, haulroad maintenance costs are a huge expense, and most companies are forever looking at ways to reduce this onerous burden.
Mark Twain once famously noted: “Everyone talks about the weather, but no one does anything about it.” He was right about the weather – it’s a huge topic of conversation at mine sites during Australia’s notorious wet season – however there IS something you can do about it. Or at least its after effects on haul roads. It all comes down to road management and innovation… Mining companies dread the wet season. With expensive machinery and personnel standing around idle, the downtime can quickly
Regardless of the type of material you are producing (eg coal, ore, etc.) and the physical location of the operation generating the dust (ie. underground or above ground mining) the quickest, easiest and most effective way to control errant dust is with a dust suppression system. A well designed and properly installed dust suppression system is an economical long-term solution that, with regular maintenance, can provide years of trouble-free performance.

The date: May 1997. The place: Blackwater, QLD. The location: The Blackwater Mine Haul Road The incident: A water truck was operating on the haul road. Unbeknown to the truck driver, a light vehicle (4WD) was approaching from behind. As he neared an intersection, the water truck driver indicated to turn right. The LV driver, thinking that he was being signalled that it was OK to pass, did so…with fatal consequences. This true story graphically demonstrates why purpose-built Light Vehicle Roads
When it comes to haulroad safety at mine sites, it’s often a ‘feast or a famine’ scenario: the surface is either too dry and dusty, or too wet from excessive watering. Both aspects of haulroad safety are problematic, but in this article let’s concentrate on the latter – overwatering, which can often result in an uncontrolled and unsafe work environment. It’s a big haulroad safety problem that can lead to a stack of incidents, usually as a result of: Out of control sliding & skidding Corner
The trouble with haulroad construction on mining sites is that the haulroads are seen as only temporary, or at best semi-permanent. As such, they are often built in a hurry, with minimal expertise, and a lot of shortcuts taken to bring them into budget. However, skimping on haulroad design and haulroad construction can actually have the opposite effect, leading to exorbitant road maintenance costs, prohibitive operational costs and impact upon production rates and safety. The mistake many
As innocuous as it seems, water on haul roads – regardless of whether it is delivered organically by Mother Nature or via water truck – has a negative impact on the life of mining truck tyres Of course, there are many aspects that affect the life of your haul road vehicle tyres…such as the quality of the sub-base, camber, temperature, superelevation, and the condition of the running surface (haulroad defects, surface roughness, and so forth). Yet one of the biggest impediments to maximising
There are many methods of dust suppression available in Australia, however the best dust suppression solutions are those that incorporate HydroWet, a concentrated surfactant specially formulated by Dust-A-Side to improve the wetting ability of water, particularly on hydrophobic materials such as coal and other fine ores. The main reason for its proven success is the fact that as a superior wetting agent, HydroWet helps to lower the surface tension of water particles, leading to smaller water
Having spoken to a lot of mining operations managers and superintendents recently, Dust-A-Side Australia have come to realise that there is some confusion as to the difference between Dust Suppression and Dust Prevention We hear comments such as: “But aren’t they the same thing?” and “Can’t we just hose the material down and be done with it?” In this article, we’ll look at the difference between Dust Suppression and Dust Prevention, and explain why it is appropriate to use them for different
Many mine managers consider re-sheeting haulroads to be a necessary evil, a task that has to be performed on a yearly basis. A lot of mines factor the cost of re-sheeting into their annual maintenance budgets, accepting it as a “normal” operational expense that affects the total cost of ownership of the asset. In high rainfall areas such as northern Australia, re-sheeting the surface wearing course material– often seen as the ‘sacrificial’ course – has to take place even more regularly. As you
Conveyor dust can be a massive problem for mine superintendents and port managers. There are the inevitable health and safety issues, pressure from the public (particularly around ports) and intense scrutiny by the Environmental Protection Authority. On top of that, there are operational issues. Conveyors are purpose-built to perform in the harshest environments, but adding unnecessary dust and material build up to bearings, motors and other moving parts can lead to breakdowns, malfunctions and
If there’s one thing every mine site superintendent knows about haultruck tyres, it’s: “The more they turn, the more we earn.” That truism is important because with each tyre costing roughly the same amount as a Mercedes Benz, the cost of replacing haul road tyres is one of the major expenditures in any mining operation. So if there were some way to increase the performance and extend the life of your haultruck tyres, you’d definitely want to know about it, right? There is. With our Road
Fog cannons, sometimes known as mist cannons, are fast becoming a popular option for dust suppression at mine sites, demolition sites and construction sites. They are ideal for use in scenarios where visible dust, rather than respirable sized dust, is a major problem. In this article, we’ll look at how fog cannons operate as well as the types of circumstances they are most effectively used in as a dust suppression solution. What is a Fog Cannon and how does it work? In simple terms, a fog
Case Study: Custom Dust Suppression System at an Australian Mine Site Reduces Respirable Dust by 78%
Dust-A-Side have designed, installed, commissioned and are currently fine-tuning a dust suppression system at a mine site preparation plant* in Australia. *The clients’ name has been withheld for confidentiality reasons. About the site At the plant, which is an intrinsic part of a 27,000+ hectare mine site, export-quality hard coking coal is processed and made ready to be loaded onto coal trains for the over 350km trip to the coal terminal. With approximately 12 million tonnes of rich black
Haul roads can feel like a bottomless pit of expenditure for miners. The trouble with haul roads is that most mines see them as only temporary, or at best semi-permanent. So roads are often built in a hurry, with minimal expertise, and a lot of shortcuts taken to bring them into budget. As many mines have experienced first hand, a poorly designed road will ultimately lead to premature failure, resulting in exorbitant maintenance and operational costs. Furthermore, when building or repairing
Achieving effective dust control for tailing dams can be real a headache for mine operators. Control measures not only need to be cost-efficient, but operationally effective too. In this article, we’ll take a look at how to best achieve dust control at tailing dam sites on an ongoing basis. The challenge tailing dams present for dust control Tailing dams are designed to permanently hold waste material which is produced during the process of grinding up and separating minerals from ore. When
One of the biggest hazards for workers across mining, construction and bulk material processing is actually something quite small…fine dust particles. Breathing in dust and long-term exposure to dust has been proven to cause mining related dust diseases that affect the eyes, lungs, throat and even the nervous system. Fugitive dust has numerous generation points throughout an underground or open-cut mine including haul roads, stockpiles, conveyors and hopper bins. Processing activities such as
Constructions sites of all sizes and types pose a unique set of dust control challenges. There are numerous ways dust can be generated and each dust generation point needs to be dealt with separately. Whenever earth is being pushed around by dozers and graders, the bare earth will inevitably start blowing around in the wind, causing dust and other contaminants to become air borne. At larger construction sites, unsealed dirt roads are an obvious and major contributor to dust. Additionally,
Achieving an effective and consistent dust management solution for mine roads is an ongoing challenge for mine operators. This is mainly because there is no single product or process that can be used to achieve optimal dust control across an entire mine site. Consider that a typical mine site is made up of both permanent and short term roads, ramps and flat roads, all of which will need to cope with varying types and volumes of traffic. So it stands to reason that a dust control measure which
