Tailings monitoring tech making headway in African miningFrom Creamer Media’s Mining Weekly Geotechnical instrumentation supplier, installer and monitoring company Terra Monitoring – a subsidiary of geotechnical services group GeoGroup – is installing a ShapeArray electronic monitoring system for a mining company in South Africa. ShapeArrays monitor the deformation of soils a ...

Terra Monitoring, a sister company of GeoGroup is now an installer of ShapeArray™.ShapeArray™ are automated inclination monitoring instruments that are widely used to measure the deformation of soil and structures in the Geotechnical Monitoring fields. They are particularly well-suited for long-term monitoring applications due to their durability and reliability. These units ca ...

We recently had the privilege of participating in a heartwarming community upliftment initiative at a rural preschool in Steelpoort, South Africa. As a team, we were excited to donate educational items, blackboards, whiteboards, furniture, and a soft carpet to the preschool. We also donated food parcels and a gas stove so that the teachers would have the tools to prepare meals ...

Dissipation testing is an in-situ testing method that measures the change in pore water pressure over time. Dissipation testing is used to assess the drainage and consolidation characteristics of soil, which are important factors in many geotechnical fields.Dissipation testing is typically performed using a piezocone penetrometer (CPTu). The CPTu is a device that measures the c ...

In September, our team of Geomech Africa drillers arrived in the North West Province of South Africa to begin a three-week drilling project. The brief was to conduct geotechnical drilling and core recovery at twelve holes, each 20 meters deep, at three different sites. These sites were 25 kilometres apart, so the team divided into two teams and worked simultaneously.The team us ...

For our contribution to Arbor Week in early September, the GeoGroup donated ten trees to Resthaven Ministries located in Rossettenville in the South of Johannesburg. These ten trees were delivered to their premises where our team members dug the holes and planted the trees for the residents of both the retirement home and the orphanage. In a few years' time, these trees would h ...

During the course of the past months, both our teams have made significant progress drilling in Steelpoort. ...

Sonic is an advanced method of drilling which uses a high-frequency energy known as an oscillation that is generated inside the Sonic head. During drilling, the high-frequency oscillation is transferred down the drill string to the bit face at various Sonic frequencies (0hz to 150hz). Simultaneously rotating the drill string (Max 90rpm) evenly distributes the energy and impact ...
