An adaptive method for removing power frequency interference is proposed by combining seasonal trend dispersion(STD) decomposition with recursive least squares(RLS). This method utilizes STD decomposition to extract the seasonal component containing power frequency interference from microseismic waves, which serves as the reference signal for RLS, and dynamically updates the algorithm coefficients to make the calculated signal approach the power frequency interference signal. Simulation experiments were designed by superimposing 1 set of microseismic waves without power frequency interference with 3 different types of power frequency interference. The finite impulse response(FIR) filtering, wavelet threshold(WT) filtering, and the method presented in this paper were used for processing. The results indicate that the method in this paper can effectively remove power frequency interference while fully preserving the key time-frequency characteristics of microseismic waves. Furthermore, the application of this method to the microseismic monitoring data processing of Taoyuan coal mine has verified its feasibility and reliability in engineering applications.
