Control of respirable dust in conventional coal mining

Coal cutting and drilling are the two dustiest operations in the conventional mining cycle; MSHA reports that the national average for these two operations is 1.1-1.2 mg/m3. In spite of the efforts to reduce respirable dust concentrations, not all mines and/or sections are in compliance with the 2.0 mg/m3 regulation.

coal mining Conventional mining Early European miners wedged coal out of the seam or broke it loose with a pick. After explosives were introduced, it was still necessary to undercut the coal seam with hand tools. The advent of steam, compressed air, and electricity brought relief from this hard, dangerous work.

Coal Mining and Processing The National Academies Press

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) decommissioning the mine and releasing the property for post-mining use.

The three main types of surface coal mining are strip mining, open-pit mining, and mountaintop removal (MTR) mining. Surface Mining: Strip Mining Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips.
