Due to their operating cost efficiency, draglines commonly excavate the waste passes immediately overlying the valuable coal seams. As such, deep pits containing two coal seams are usually mined using a pre-strip pass and two dragline passes. The first dragline pass excavates the overburden overlying the upper coal seam with the second dragline pass excavating the interburden and
