2 Introduction
2.1 System overview
The Quarryman Pro is a field instrument which combines reflectorless laser ‘point and shoot’ measurement
technology with high-speed automatic scanning. The unit can be used for conventional total station survey methods
as well as 3D laser scanning. Complete scenes and objects in view at ranges of up to 750 m can be surveyed.
The instrument employs the ‘time-of-flight’ laser measurement technique to measure ranges to rock faces and other
objects without the need to place reflectors on the target. This allows accurate measurements to be made of
inaccessible points such as quarry faces and stockpiles.
Versions of the Quarryman have been used in the field for over 30 years. This experience has ensured that the
instrument has been developed very specifically for its intended applications. It is designed to be very simple to use
and is capable of operating in the harshest environments.
Selective use of the FastScan feature enables single or multiple high-definition scans to take place, highlighting
rock features and anomalies.
The Quarryman Pro will observe 250 points per second, or up to 900,000 points per hour.
Quarryman Viewer
software is supplied with the Quarryman Pro. This can be used to process the survey, and then
to edit, view and export the data. Many third-party packages will also take in data directly from the Quarryman Pro
for specialist profiling and volumetric applications.
2.2 Blast design package
Carlson is able to provide a complete ‘blast design’ package to help quarry operators optimize their fragmentation
