Development of sensors for monitoring seismic response and strata behaviour during underground and surface mining operations, including sensors for the assessment of velocity of detonation (VOD) of explosives.
Development of seismic sensors for both nearfield and farfield monitoring and establishment of laboratory-scale calibration setups, where seismic events are generated through controlled blasting in open air and within concrete or rock blocks.
Development of experimental setups to investigate the trigger mechanisms in VOD sensors.
Development of finite element-based explicit dynamics models, with model responses providing insight into optimal sensor placement.
Facilitation of comparative analysis between the developed sensors and existing commercial systems through these setups.
