Formatted abstract
The R13/14 Corridor is a region of steeply dipping coal located between two active dragline pits, R13S “Fiddlewood Pit” to the north and R14N “Grevillea Pit” to the south. For the planned R14N S21 to S25 dragline pits, a series of northward progressing box cuts are required, the end walls of which are to skirt around the edge of this corridor. In the past the R14N dragline pits did mine into this steeply dipping region, however a series of lowwall failures and generally difficult mining conditions resulted in Saraji to decide that the steeply dipping coal should remain as a corridor, which could be mined in the future.

Many of the issues surrounding the R13/14 Corridor have in the past been known by only a few of those people who have the responsibility over this region. The constantly changing site conditions surrounding the corridor has reached a point whereby if immediate action is not taken, a substantial volume of high quality coking coal will be sterilised and the planned progression of the R14N strips down dip will require revision.

This thesis addresses the main issues that trouble this area by producing a series of excavation designs that utilise currently accepted mining practice and tie into the mining schedule for Saraji Mine. The ultimate goal is to create an extraction strategy that will assist Saraji in the planning of mining operations in the R13/14 Corridor, which prepares the region for the northward progression of the R14N box cuts, while minimising both coal sterilisation and the impact upon the as yet unplanned R13S and R14N prestripping operations.
