Mine Microseismic Signal Denoising Based on a Deep Convolutional Autoencoder

Figure 6

Denoising examples. (a, c) The effective signals (Z component) in the time-frequency domain. (b, d) The effective signals (Z component) in the time domain. The time-frequency coefficients and waveforms of the effective, noise, and noisy microseismic signals are plotted in panels (i), (ii), and (iii), respectively. The recovered effective signals in the time-frequency domain and their time-domain waveforms are shown in panels (a, c) (iv) and (b, d) (iv), respectively. Panels (a, c) (v) and (b, d) (v) show the recovered noise signals in the time-frequency domain and their time-domain waveforms, respectively.
