With this especially engineered product, moisture does not absorb into the material creating a cake-like paste as seen with standard rock dust products in wet environments. Imerys’ new product is more hydrophobic than conventional rock dust and does not absorb water as readily, allowing it to remain dispersible throughout the mine, from the roof to the ribs, to puddles of water on the floor, providing assured functionality in case of an explosion. The new product is designed to require less maintenance and less refreshing for mine operators, expecting to reduce costs and application time. The product is available in trial quantities and is set to be widely available in 2015. www.imerys-carbonates.com
