The CDEM-1000 meets the needs of mining operators, safety inspectors and regulators when following the coal dust sample collection guidelines as described in Bureau of Mines Informa-tion Circular I.C. 7113 or MSHA Hand-book, Number PH-08-V-1. The CDEM-1000 is intended to be used as a screening tool to help manage daily rock dusting operations and to help mitigate the explosion hazard potential by identifying inadequate rock dusting applications. The CDEM-1000 can also be used as an effective tool by mine operators to help determine a more efficient balance between coal dust and rock dust levels.
