Dust Control
Dust control is an issue that has become very important to manage on various projects throughout the mining and civil industries due to health and safety concerns, EPA regulations and also to assist with productivity.
Due to the incredibly dry climate in parts of Australia, and some of the most stringent safety and environmental management laws in the world, a good dust control strategy is one of the most important considerations in an Australian project, be it mining, construction or civil. Long-term harmful impacts of dust exposure including exposure to silica dust can cause lung disease and lung cancer, chronic obstructive pulmonary disorder (COPD), and silicosis. These conditions can greatly decrease the patient’s quality of life and shorten their lifespan. Strict laws are mandated by local councils, the EPA in each state and by Worksafe. perhaps the chief long-term threat to worker safety at a mine site is suspended particulate matter, or dust, generated by the daily operations of mining.
Australia produces approximately 6% of the world’s coal and nearly 80% of our coal comes from open cut coal mines (compared with 40% globally).
Open cut mines produce a number of challenges in relation to dust control and air quality due to the inevitable production of respirable sized dust,
Respirable dust (PM10) refers to dust which is typically less than 10 microns in size. Invisible to the naked eye, respirable dust is the type of dust which can cause everything from vision impairment to major health risks such as black lung disease.
What are dust suppression systems? – these are wet or dry techniques that use either dust suppressants or baghouse filters to bind or collect fine dust particles respectively. The dust suppression systems must be placed strategically for the dust suppression to be effective.
Wet Dust Suppression Systems vs Dry Dust Suppressions Systems
Dust suppression systems are used to control dust through various techniques. Our discussion compares wet dust suppression systems to dry dust suppression systems. The application of dust suppression systems is for dust particles generated in different industries. Dry dust suppression systems use collection systems that implement bag houses with fabric filters that vacuum dust from the source and collect it in a hopper for disposal. In wet dust suppression systems, a wet dust suppressant in the form of a spray (mist or fog) is commonly used to control fugitive dust particles. The most common form of wet dust suppression systems are water spray technologies.
Mining Dust Control
In the mining & civil industries the most common dust suppression systems use what is known as the wet technique. There are many and varied forms of ‘wet’ dust control or mitigation techniques, which include constant wetting, dust fogging or the use of sprinklers to provide dust suppression in a particular area.
Points of high use or areas of constant product movement such as crushing plants, blasting areas, conveyor cross overs, ROM Bins, conveyors & load out areas predominately utilise fixed dust control systems such as fogging, misters, sprinklers as dust suppression measures.
Wind erosion of tailings dams & ash pits are also an major issue, utilising a similar method of permanent dust control systems to mitigate airborne dust. As this infrastructure normally covers a smaller area comparatively the use of Dust Suppression Towers, Dust Control Sprinklers, Fog Cannons and Misting Jets.
Stockpile Erosion & wind erosion of overburden is also a major source of Respirable dust across mine sites, ports and civil sites. Depending on the site specifics stockpiles are wetted using mobile water trucks with cannons, Mobile Fog Cannons, or fixed infrastructure such as pole mounted dust suppression sprinklers.
It is the responsibility of mining companies to deliver comprehensive dust control solutions in order to meet Ambient Air Quality NEPM standards. This is essential for preventing harm to the health of both workers and the wider community.
With so many options it is difficult to ascertain which system will work best for your site.
Liquimech have a Range of both fixed (permanent ) Semi-permanent and Rapidly Deployable relocatable dust control systems to suit any requirement All of our systems can be triggered by remote control sensors and programmable logic controllers with fully automated, self-cleaning water filtration systems.
Haul Road Dust suppression is one of the most important in mitigating airborne dust onsite with 40% of PM10 in mines coming from haul roads. Dust control for haul roads is primarily undertaken by water carts with sprays that keep the roads moist to minimise dust pollution. Water Carts are filled using overhead truck fill systems.
