Ground Monitoring Devices

Having functional ground monitoring devices in mines is essential for the infrastructure of the tunnels and the safety of the workers. These devices ensure that electrostatic charge remains at a safe level to prevent the risk of explosions or fires.

Ground Monitoring Devices

Ground monitoring devices allow operators to analyze the stability of a mine or tunnel by continuously monitoring the integrity of an electrical grounding system and automatically responding if a problem occurs.  

Ground monitoring is especially important in hazardous areas where there is a significant generation of electrostatic charge, such as when mixing liquids or at filling tanks and loading bays. Active ground monitoring will monitor the connection to an object at risk of electrostatic charge and signal to workers if it is secure. 

These devices ensure that electrostatic charge remains at a safe level to prevent the risk of explosions or fires. 

Ground Monitoring Device Manufacturers

Carroll Technologies has provided safety and electrical equipment to mines across the US for more than 40 years. Carroll has searched the market for only the most rugged and reliable devices, and can work with customers to recommend the most suitable solutions for their application. When it comes to ground monitoring devices, Carroll offers a broad range of products from trusted manufacturers such as  Simplified Mining Instruments (SMI), AMR PEMCO, Becker/SMC, and MCI. 

Simplified Mining Instruments (SMI) provides a range of ground monitoring devices which help to predict and prevent possible mine collapses, including the Sag Flag Roof Monitor which acts as an early warning system that helps to identify ground movement before it becomes an issue, and the SMI Miners Borehole Camera, which is used for the inspection and monitoring of boreholes as small as 1-5/8″ diameter and up.

AMR PEMCO has been a pioneer for ground monitoring devices for mines since 1975. It’s portfolio includes the only MSHA-approved high-voltage pilotless ground monitor on the market.  

Becker/SMC provides a wide range of sophisticated electrical control systems, including Servic Sentinel Ground monitors for low-medium voltage circuits, as well as high voltage ground monitors.  

MCI is a supplier of advanced power solutions. In addition to aircraft instruments, MCI provides a range of ground power units that are ideal for ramp maintenance and emergency starts. 

Finding the right ground monitoring device depends on where in the mine it is being utilized and the voltage of the system it will be overseeing. Carrol Technologies works with mines to ensure that their safety systems are optimised, including around the clock technical assistance, as well as rapid response to emergency situations and a spare parts inventory worth more than $7 million from 70+ manufacturers at 13 distribution centres across the US. Carroll also performs factory-authorized repair and certification, maximizing the value of customer investment.
