Publication - NOISE REDUCTION OF BELT CONVEYOR

2021-10-17  NOISE REDUCTION OF BELT CONVEYOR TRACKS Gondek, H.; Kolman, J.; Bohac, D. Abstract: Today, there are high demands for ecological solutions to the problems associated with all human activities, and therefore there is great pressure on surface mines to contribute to the reduction of dust and noise in the extraction of raw materials.

Noise Reduction of Steel Cord Conveyor Belt Defect ...

In order to reduce the noise of a defect electromagnetic signal of the steel cord conveyor belt used in coal mines, a new signal noise reduction method by combined use of the improved threshold wavelet and Empirical Mode Decomposition (EMD) is proposed. Firstly, the denoising method based on the improved threshold wavelet is applied to reduce the noise of a defect
