Discuss the role of monitoring during support installation to ensure that the support sequence is functioning as designed. (5 marks)

Real-Time Deformation Tracking

Instruments like inclinometers and strain gauges monitor ground movement and deformation in real-time, verifying that supports (e.g., rock bolts, shotcrete) are effectively controlling ground stability. If excessive deformation is detected, the support sequence can be adjusted immediately to prevent potential collapse.

Load and Stress Measurement

Sensors measure the loads and stresses on support structures, such as steel ribs or reinforced linings, confirming they are bearing the anticipated loads. This feedback ensures the supports are functioning within their design capacity, highlighting if additional reinforcement is needed.

Early Detection of Ground Instability

Monitoring systems detect early signs of instability, like unexpected settling or ground relaxation, allowing for immediate corrective actions in the support sequence. This proactive approach minimizes risks in challenging conditions, especially in weak or fractured ground.

Verification of Installation Timing

Monitoring validates that supports are installed at the right intervals, confirming that the timing aligns with design parameters for effective load redistribution and deformation control.
