The DMT Slim Borehole Scanner is the ideal solution for structural and geotechnical analyses of rock and soil and geotechnical investigations in geology and engineering.
With seismographs of the SUMMIT family, DMT offers a modular seismic data acquisition system for a wide range of tasks in seismic exploration (e.g. 2D/3D reflection seismic as well as near surface investigations) as well as for passive micro-seismic monitoring and vibration measurements.
Digital Core Imaging
DMT CoreScan3 is a portable core imaging device developed for drill core image acquisition, storage and evaluation of full and slabbed core.
Images can be combined with CoreBase software with every other information from the Borehole.
Optical Borehole Inspection
The DMT Slim Borehole Scanner is the ideal solution for structural and geotechnical analyses of rock and soil and geotechnical investigations in geology and engineering. The tool for optical inspection and documentation offers highly precise monitoring for slim and short boreholes and early detection of a possible fault in tunnel construction as well as other applications. In addition, it can be employed as a mobile monitoring tool for the determination of fracture widths.
The device can be manually operated with a borehole diameter between 1" and 1.8”. It is lightweight and easy to use. Therefore, it is ideally suitable for regular inspection and scanning of, for example, roof bolt holes drilled in rock for tunnel construction projects.
During insertion in a drilled hole, the scanner is illuminated by a ring of LEDs. The camera captures 360° images from the walls of the borehole. These images are stacked slice by slice to provide an image of the complete borehole. This method of frequently sampling boreholes delivers optimized data where every set of measurements or every borehole can be compared with each other.

High-tech core logging tool
DMT CoreScan3 is a portable core imaging device developed for drill core image acquisition, storage and evaluationof full and slabbed core. Furthermore, whole core boxes can be scanned in one image.
Full core is rotated 360°around its cylindrical axis while the line-scan camera, positioned parallel to the axis of rotation, scans its surface.Full core is scanned at a rate of ~20 sec/m and the image can be stored as BMP, PNG, TIF or JPG files.
