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 top of mountains is ...
EQUIPMENT SELECTION b) Face Supports. While it is frequently argued (correctly) that all items on a longwall face have to be considered as parts of an integrated unit and be fully compatible, it cannot be denied that poorly designed and inadequate roof supports are likely to have a greater effect on results than other items, and to that extent are more important.
