Carlson Introduces the New VS+ Stope Surveying System


Carlson Void Scanner+ (VS+)

MAYSVILLE, Kentucky, U.S.A. (November 2019) — Carlson Software has just released its new Void Scanner+ (VS+), a fully wireless surveying system designed to be used for underground surveying. The system is an upgraded model of Carlson’s standard Void Scanner.

Engineered to scan in extreme environments, the ruggedized VS+ system is designed to be deployed into potentially hazardous locations — allowing operators to map underground cavities safely. The information collected by the VS+ can be viewed in real-time and can provide mine site managers the information needed to optimize production, review extraction, backfill operations, and monitor problems with ore loss and dilution. It can also be used for ore pass monitoring, mine design management, underground blast planning, drive surveys, and pre and post underground evacuation planning.

The VS+ includes an onboard battery and wifi connectivity to a tablet computer from up to 50 meters. The fully wireless capability increases deployment speed and operation. Carlson’s VS+ can be deployed via stock boom or operators can create a customized boom, tripod, or crane to enable safe operation where access is limited or dangerous.

A full scan with one-inch increments can be completed in less than 12 minutes with a 200 point-per-second scan rate, 360-degree horizontal scan, and a vertical scan extent of 270 degrees.

Operators can run the free scanning software, Carlson Scan, on a tablet computer to view the scan and analyze recorded data. Carlson Scan automatically connects to the VS+ and enables full remote control of the system. The post-processing tools can be used to analyze, geo-reference, and edit data as needed. Geo-referenced point clouds or modeled surfaces can be exported in industry-standard formats. The exported data can then be integrated with popular mining and CAD packages, including Carlson Mining modules and Carlson Point Cloud.

The VS+ is part of Carlson’s Laser Measurement Division (LMD), which includes: C-ALS® Gyro, Void Scanner, Quarryman® Pro, Rodded and Cabled Boretraks®, and Merlin.
