Characterisation of Overburden Rock Mass and Top Coal Delineation Using Triaxial Drill Bit VSP Method

Get Report
C1902001/05/2014
Author: Shivakumar Karekal, Nobukazu Soma and Toshiyuki Tosha | CSIRO, National Institute of Advanced Industrial Science and Technology (AIST), Japan

Coal loss and coal dilution is a serious problem in open pit coal mines. Poor structural characterisation of rock mass can lead to poor fragmentation which could hamper the productivity of draglines often used in cast blasting to remove the overburden. Coal loss and dilution can amount to ....  read more
