Cleveland Potash has purchased 3D Laser Mapping’s ZEB1 hand-held laser mapping system to map underground workings, complete stock surveys and comply with health and safety legislation at Boulby mine in North Yorkshire, UK.

The ZEB1 mobile mapping system will reduce the survey mine workings time, increase the amount of data available to mine managers and enable for the introduction of new working practices.

Cleveland Potash initially used traditional chain and offset surveying with manual data entry before upgrading to total station measuring.

The company deployed the ZEB1 mobile mapping system in 2013, which increased the efficiency of underground mapping, required by law for health and safety compliance.

3D Laser Mapping said the ZEB1 is also being used to capture volume measurements for the creation of monthly tonnage reports, to survey outdoor stock piles and silos and to produce detailed drawings and plans of the mine workings.

Mine surveyor William Hedges said that the ZEB1 saves time both underground while surveying and back in the office data processing.

"Using the total station it used to take about an hour and a half to survey each of our five districts plus data processing time," Hedges said.

"This meant that the survey cycle was a minimum of a week. Using the ZEB1 we can complete it all in one day. This allows us to capture and produce survey measurements for a multitude of other applications."

Australia’s national science agency CSIRO developed ZEB1, which is being commercialised by the UK-based 3D Laser Mapping.

The system uses robotic technology called simultaneous localisation and mapping and includes a lightweight laser scanner mounted on a simple spring mechanism.
