Local Acceleration Monitoring and its application in physical modelling of underground mining

A Micro-Electro-Mechanical Systems (MEMS) inertial sensor was introduced to perform Local Acceleration Monitoring (LAM) in a physical model to showcase mining-induced strata movements. To prove the feasibility of LAM, a physical model experiment was performed using four sensors mounted on the roof strata. Acquired acceleration signals were processed by a moving average and median filter, analysed with respective trend variation and fluctuation...
