Monitoring and Sampling Approaches to Assess Underground ...

Forms of coal range from soft (lignite) to hard coals (bituminous and anthracite) with higher carbon content. Anthracite, historically mined in Pennsylvania, has the highest carbon content (86 to 97 percent) and now accounts for only around 8 percent of coal production in the United States and percent of the nation’s underground mining (EIA, 2017a,b).

An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces. The panels are the working sections of the production operation. Depending on the mining method, a working section can have one or more working faces. The mining activities that ...

Lessons learned: sampling for bioaerosols in underground ...

Situation: Are miners exposed to atypical levels of bioaerosols in the mine environment? To answer this question, the National Institute for Occupational Safety and Health (NIOSH) developed methods to sample face areas of underground coal mines which use untreated surface water in the dust suppression systems.

Standard Practice for Collection of Channel Samples of ...

A properly collected face channel sample that includes the total coal bed interval provides a sample that is a representative cross section of the coal bed at the point of sampling. Channel samples are taken for subsequent testing needed for evaluation of coal quality and characterization for commercial evaluations, for planning of mining operations to maintain coal quality, for the ...
