Current Research

This research takes a holistic view of the excavation industries by looking at the interplay between equipment and the ground characteristics with the aim to produce a ‘fit for purpose’ excavation index to optimise the excavation process. 

With recent changes in technology, such as the development of more powerful machinery, the development of remote sensing technology and numerical modelling for improved rock mass characterization, existing methodologies for assessing the ‘excavatability’ of rock masses are out-dated for excavation design purposes. Significant benefits, through improved efficiency, can, therefore, be made across various engineering sectors with the development of an up-to-date, fit-for-purpose ‘Index’, where continuous excavation in rock is involved. 

This research is carried out by industry collaboration and the analysis of a range of empirical case studies that reflect the advancement in equipment technology as well as productivities within a range of different geological and geotechnical environments. 

This research is funded by the Engineering and Physical Sciences Research Council (ESPRC), under the supervision of Professor John Coggan and Professor  Lars Johanning
