Strata management and ground control warning systems are fundamental components in ensuring both the safety and efficiency of your mining operation. With over 30% of accidents and fatalities in underground mines occurring as a result of rock-fall - with most of these incidents occurring close to mine entrances and near the mining operation - having a mine-wide monitoring solution and a series of advanced warning systems to identify structural damage and potential risks, enables you to protect your personnel and avoid incidents, allowing you to continue operations at maximum safety and efficiency.

At Trolex, we offer the most advanced array of strata management and ground control technology. Our range of  extensometers and telltales are established as the world’s leading product range for measuring roof movement in underground excavations and boreholes, as well as being a critical part of any underground safety environment.

Our range of ground control equipment includes simple mechanical wire extensometer visual-warning telltales, through to complex remote-reading telltale systems that feed into a project SCADA (Supervisory control and data acquisition) system or other interface to provide a real-time analysis of strata movement and potential hazards.

Our extensometers and telltales have been operating in the harshest mining conditions for over 40 years and our systems have been proven in independent studies to radically reduce incidences of injury to personnel and expenditure on support collateral, as well as improving mine efficiency, borehole safety and reducing down-time.
