Improving Signal Detection Range of Active Seismic Monitoring in Mines

该项目将开发新一代传感器，该传感器将处理来自有源的传入地震波，以实时准确地估计地下岩体的性质。这将导致更安全的采矿作业，从而减少伤亡人数。概率图模型将用于融合来自不同传感器的测量，以产生更准确的岩体估计。一种新的低成本震源将激发大面积的岩体，以连续监测采矿引起的应力和裂缝密度的变化。这将产生能够显著改善采矿作业和提高澳大利亚采矿部门生产力的方法。

This project will develop a new generation of sensors that will process incoming seismic waves from an active source to accurately estimate the properties of underground rock mass in real time. This will lead to safer mining operations that will decrease the number of injuries and deaths. A probability graph model will be used to fuse measurements from different sensors to produce more accurate estimates of the rock mass. A new low-cost seismic source will excite large areas of rock mass for continuous monitoring of the changes in stress and fracture density caused by mining. This will lead to methodologies that will significantly improve mining operations and increase Australia’s productivity in the mining sector.
