Rock Fracture Monitoring Based on High-Precision Microseismic Event Location Using 3D Multiscale Waveform Inversion

Figure 1

2D plane projection location of sensors and spatial orientation of the inclined plane. The blue triangles indicate practical locations of the sensors for the MS monitoring system deployed in the Yongshaba mine, and the cyan triangles denote the vertical projection location of sensors onto the 2D inclined plane. The inclined plane is determined by the least square value of summation of the vertical distances from all sensors to a spatial 2D plane. The colored background corresponds to the altitude of the inclined plane. The upper left corner shows the side view of the sensor distribution and the spatial orientation of 2D projection of the inclined plane.
