Mining and Tunneling

Precision accelerometersinclinometers, and load cells play crucial roles in mining and tunneling applications. They provide critical information on structure stability and safety, precise acceleration measurements for equipment, structures, and personnel underground and monitoring forces on equipment and structures during excavation, and material handling.

 

Inclinometers

In mining and tunneling, inclinometers are crucial for ensuring underground structure stability and safety. They measure the angle of inclination or slope of walls, providing real-time data to monitor ground movements and detect hazards like rockfalls or collapses. Inclinometers are also used in slope monitoring to detect changes in slope angles caused by excavation stress, allowing engineers to implement preventative measures early to protect workers and infrastructure.

The model T233 dual-axis inclinometer in either Voltage or Current output can provide data about parallel or perpendicular displacements on a bore machine, ground movement, and excavation. The positioning of the inclinometer on the bore wheel provides a solution to horizontal displacement in two perpendicular planes and movement orientation.

Displacements versus time and distance to the tunnel face were used to visualize the effects of tunneling on the inclinometers, to calculate displacement magnitude, and direction, and to identify and understand the cause of probable trends, and potential concerns or adverse situations.

 

Accelerometers

Accelerometers are used in mining and tunneling, providing precise acceleration measurements for equipment, structures, and personnel underground. They monitor machinery like haul trucks and drills, detecting vibrations and impacts to predict failures and optimize maintenance. They also monitor tunnels and excavations for stability, detecting movements from blasting or settlement. In personnel safety systems, accelerometers detect sudden movements and alert for hazards.

 

Load Cells

Load cells are vital in mining and tunneling, monitoring forces on equipment and structures during excavation, and material handling. They measure compression, tension, and shear forces, ensuring the safe operation of heavy machinery underground. In mining, load cells are integrated into equipment like conveyor belts and crushers to measure material weight, optimizing production and preventing overloading. They’re also used in support structure design to assess load distribution and maintain excavation stability. In safety systems, load cells monitor the weight of equipment like hoists and scaffolding to prevent accidents.
