متن کاملBreakage and fragmentation modelling for underground production blasting applications
A review of breakage and fragmentation modelling literature has shown that only a few methodologies have been specifically developed for applications in underground production blasting. These approaches however, have applied empirical relations that do not adequately consider ring blasting geometries; have failed to appropriately respond to changes in basic design input parameters; and have pro...
متن کاملA Geographic Information Systems Approach to the 19th Century Excavation of Brixham Cavern, Devon, England
The oldest known spatially-explicit archaeological excavation, conducted in Brixham cave, Devon, in 1858, is reconstructed using geographic information systems technology. Two dimensional plots of individual fossil taxa and flint artefacts demonstrate the utility of the technique for elucidating taphonomy and palaeobiology.The cave served as a den for hibernating brown bears, as a den for hyena...
متن کاملExcavation of an Underground Theater below the St
This paper describes part of the construction of a second theater in the underground museum complex, below the Gateway Arch in St Louis. Given the needs for relatively quiet, non-intrusive rock removal, and yet precise cutting within the museum complex a method of using low pressure (35 MPa) abrasive laden waterjets was developed for cutting the vertical walls of the theater down to a depth of ...
متن کاملDevelopment of a Mobile Manipulator for Underground Excavation Task
A national research and development program on Underground Development Technology has started in 1989. In this program, a basic study of a excavating robot has been done at the Mechanical Engineering Laboratory. This paper describes an experimental mobile manipulator for the excavating task. Four legs and a pair of crawlers are equipped with the mobile platform, and a manipulator is set on it. ...
