Dust control is of course widely needed and no more so than on tailings facilities. Soilworks®, a global specialist in mining dust control, has introduced a new, innovative approach to controlling dust with industry-leading underground haul road and mine tailing products that are safe for the environment.
From open, wind-blown tailings impoundments and dam wall erosion, to dusty underground drifts, ribs and haul roads, Soilworks is known for its consistency in producing quality solutions that solve a range of problems.
“Our extensive experience and cutting-edge technologies provide the unique ability to solve the most difficult dust control challenges that impact each mine’s profitability and safety,” said Chad Falkenberg, Founder of Arizona-based Soilworks. “That’s why Soilworks is globally responsible for supporting mines with the necessary confidence to improve operational safety; lower operating costs and most importantly, protect each miner’s health.”
Soilworks provides what it describes as “the only patented synthetic dust control fluid for tough mining dust control projects. Durasoil® is a unique and effective dust suppressant that is environmentally friendly and provides quality performance for extended periods of time with its unique, self-healing and re-workable properties.” The colourless and odourless solution works to “wet out” any soil or aggregate to reduce airborne dust.
Engineered for today’s most challenging and intense mining dust control conditions, Durasoil has been formulated using an innovative gas-to-liquid (GTL) technology. In the GTL process, natural gas is converted into a high-quality liquid product that makes Durasoil crystal clear, odourless and formulated to meet the highest standards of environmental efficacy. The result is a safe, non-toxic composition that is capable of reducing airborne and suspended particulate matter for long periods of time.
Created with non-chloride and non-petroleum properties, Durasoil is hydraulically sprayed over surfaces with any equipment that is capable of spraying water. The product is non-corrosive to equipment and applied “as is” without dilution.
As it penetrates the soil, Durasoil coats, wets and agglomerates fine soil particles together, resulting in a re-workable, dust-free layer of soil that is non-slippery and engineered to withstand the most extreme environmental conditions from -40° to over 90°C.
After application, the treated area is ready for use and doesn't require a cure time. “Even under heavy traffic loads and intense-use conditions, Durasoil’s unique, self-healing properties remain effective from months to years depending on project needs,” the company says.
Gorilla-Snot® is another Soilworks product with a dependable reputation across the globe; a value-engineered liquid copolymer that is eco-safe, biodegradable and used to control dust and erosion on mine tailings impoundments.

“Mining professionals trust Gorilla-Snot to provide quality dust control and soil stabilisation that does not rinse away with rain, affect flotation processes or harm soils,” the company reports.
The nanoparticle molecular structures of Gorilla-Snot link and cross-link to form strong bonds between particulates, soils and aggregates. Upon application, Gorilla-Snot creates a light surface crust that remains water permeable for air and water, yet confines dust and effectively suppresses PM10 and PM2.5 particulate matter.
Increased applications of Gorilla-Snot are highly effective for water erosion control to maintain dam slope and bench stability. The environment-
friendly product is also engineered to penetrate into the ground to create a strong and resilient, yet flexible surface that can withstand heavy vehicle traffic and intense environmental conditions without harming the soil.
Air quality compliance, miners’ health, operational safety and efficiency optimisation are all part of Soilworks’ innovative approach to controlling dust within the mining industry.
“We understand that creating safe work environments and maintaining compliance are among top priorities for mining operations, so we hand-crafted a line of dust control products that get the job done without harming the environment in the process,” Falkenberg said.
