Mark National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, Pittsburgh, PA, USA ABSTRACT: Underground coal mining continues to evolve in the, and more reserves are being mined under
of the calibration process, which is essential for an OLA to produce meaningful results. OLA instrumentation has improved over the years as have the calibration procedures. OLAs are now routinely installed and operated at mines, washing plants, loadout facilities and elsewhere, but specifically as process control devices.
Each mineral processing plant is different: with varied ore types, mining equipment, and management (operating) philosophy. The evaluation and prioritisation of variables that affect the plant performance is the primary function.
outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the .

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.

the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the
