Calcium Carbonate Imerys

Coal Mine Safety. Calcium carbonate rock dust is commonly applied to the roof, ribs, and floor of coal mines to help prevent explosions from propagating through a mine. If an explosion occurs, the rock dust disperses in the air along with the coal dust, neutralizing the combustible coal dust. Food & Beverage.

Coal Dust Consolidation Using Calcium Carbonate

If it is used for coal dust control, microbially induced calcium carbonate can continuously cement coal dust by forming a calcium carbonate-coal dust consolidation layer, which inhibits coal dust, and can achieve low-cost, pollution-free, effective, and environmentally friendly dust control (Fig. 1).

Enhancement of Coal Ash Compressibility Parameters

Abstract. Microbial-induced calcium carbonate precipitation (MICP) was experimentally implemented on two coal ash materials (i.e., CA1 and CA3) to investigate the efficacy of the treatment on the hydraulic and compressibility properties of the material. Oedometers used in testing were modified to enable the injection of treatment solutions and to

About Us Airo Dust

To reduce the formation of the coal / air mix and inhibit flame propagation, most coal mine operations apply stone dust particles, such as calcium carbonate powder, to walls in a dry process. Any explosion shock waves disturb the applied calcium carbonate and cause a mixture of coal and calcium carbonate dust to be suspended in the air.
