Designing for upper seam stability in multi-seam mining
The problem of interaction resulting from mining seams above a previously mined seam has been thoroughly investigated in order to develop and evaluate methods of improving upper seam ground conditions when mining through either active or passive subsidence waves. Design criteria have been developed...
