Drilling advances in underground coal AusIMM Bulletin

The data are downloaded after a borehole is drilled and used for more accurate mine planning. One inherent weakness in current UIS drilling practices is their inability to maintain the bit within the confines of the coal seam. As a result, coal seam boreholes tend to undulate, frequently drilling out of the seam.
