The Department of Mining Engineering of Queen's University uses close range photogrammetry to inves- 
tigate the effectiveness of different explosive charges for mining operations in perma-frost, and 
for determining strikes and dips of rock formations in rock mechanics investigations 8 . Investi- 
gations are also carried out to use photogrammetrically compiled digital terrain models in surface 
mining to study mine lay-outs, stripping ratios, and location of economic pit boundaries. Waste dump 
studies are also performed 23. 
Instrumentation 
Although various types of photogrammetric cameras are presently available for close-range photogram- 
metry, there is a considerable use for "off the shelf", non-metric cameras. The photogrammetric 
application for this type of cameras and various means of calibration are being investigated, parti- 
cularly at the University of New Brunswick 13, 19, 30 . 
Projects involving the analytical plotter, which offers a definite potential in non-topographic photo- 
grammetry, have been carried out in the fields of two-media photogrammetry and architectural recording 
20, 21, 28, 29 . In addition a universal solution for model reconstruction was formulated allowing 
to use perspective bundles, as well as parallel beams of rays 27 . A hybrid solution for photogram- 
metric processing of data in the field of mining engineering is followed at Queen's University, where 
a Stereometrograph has been coupled to a Gradicon digitizer (with magnetic tape unit) and a Wang 
dedicated computer. The computer is in a time-sharing environment and controls a Wang plotting table. 
The use of Holography in photogrammetry is being investigated at Laval University 1, 2.
