The Optimum Wavelet Base of Wavelet Analysis in Coal Rock Microseismic Signals

open access: yesAdvances in Mechanical Engineering, 2014
Coal rock rupture microseismic signal is characterized by time-varying, nonstationary, unpredictability, and transient property. Wavelet transform is an important method in microseismic signals processing. However, different wavelet bases yield different

A Nonparametric Method for Automatic Denoising of Microseismic Data

open access: yesShock and Vibration, 2018
Noise suppression or signal-to-noise ratio (SNR) enhancement is often desired for better processing results from a microseismic dataset. In this paper, we proposed a nonparametric automatic denoising algorithm for microseismic data.

Seismic arrival enhancement through the use of noise whitening [PDF]

open access: yes, 2017
A constant feature in seismic data, noise is particularly troublesome for passive seismic monitoring where noise commonly masks microseismic events. We propose a statistics-driven noise suppression technique that whitens the noise through the calculation
