Abstract
Mine dust in underground coal mines is potentially explosive and must be sampled and tested for sufficient inert content regularly. The present invention comprises a pneumatic mine dust sampling instrument equipped with a specially designed nozzle arrangement that delivers a controlled pulse of air which entrains the mine dust, similar to the entrainment process that happens during a mine explosion. The entrained mine dust can then be collected and tested for compliance with applicable federal standards.
