• Description:
  With the objective of suppressing respirable dust in coal mines by foam application, a formulation was developed for making a water- based, high-expansion, and limited stability foam. A horizontal boring machine was used as a laboratory coal mining model for generating coal dust. A modified laboratory foam generator was built. Foam was applied directly to the point at which dust was being formed by the cutter of the boring machine working against a block of coal. Coal dust was sampled with an impinger and analyzed for the particle count and particle size distribution. Coal dust suppression test results on freshly generated dust have demonstrated very clearly that, in laboratory scale experiments, over 90 percent of the respirable coal dust can be suppressed by foam. These tests were run when initial coal dust concentrations were 10 and 70 million particles per cubic foot. [Description provided by NIOSH]
