ImerCoal® Moisture-Tolerant Rock Dust

ImerCoal Moisture-Tolerant Rock Dust is the new innovative rock dust solution for American coal mines with wet or high-moisture environments. When exposed to water, the new rock dust doesn’t cake, ensuring its functionality in these environments to prevent explosions from propagating throughout a mine. This provides an increased level of safety for miners and due to its durability, it is expected to require less maintenance than conventional dusts and therefore reduce costs and frequency of reapplication.
