Comparison chart of signal starting-up before first peak within blasts and microseismic events (frame (a)) and the schematic diagram of data points selecting and the trend line constructed by linear regression (frame (b), solid circles represent sampling points, and the reds represent the selected). The x- and y-axis in frame (b) represent the time and the amplitude axis in frame (a).
