Deformation Forecasting of Surrounding Rock Mass Based on Correlation between Frequency and Fracture Scale of Microseismicity

Figure 6

MS events occurred during the two stages of surrounding rock mass deformation: (a) temporal distribution of MS events between November 26 and December 14, 2013, (b) spatial distribution of MS events and their corresponding density nephogram between November 26 and December 14, 2013, (c) temporal distribution of MS events between December 23 and January 10, 2014, and (d) spatial distribution of MS events and their corresponding density nephogram between December 23 and January 10, 2014.
