Surveys were made in 11 coal mines representing five states, where 1,232 samples were collected and analyzed for incombustible content. Procedures were developed to collect and prepare for analysis dust samples from wet and damp locations. In addition, methods were developed to collect the top 1/16-inch layer of floor dust and determine the amount of coal dust in the sample. Further studies were made to try to improve the top-layer sampler, improve the standard sampler, and investigate the application of statistical methods to the rock dust compliance decision. A bibliography pertaining to explosion research and mine-dust related references is included.
