Characteristics and recognition of typical microseismic signals in rock burst mines

Meitan xuebao
Accurately identifying the type of microseismic signals is of great significance for monitoring, warning, and preventing dynamic disasters in rockburst mines. Leveraging the engineering context of Nantun coal mine, we classify five types of microseismic signals, namely mine earthquakes, blasting, coal-rock fractures, knocking, and noise. We establish a

Research on a microseismic signal picking algorithm based on GTOA clustering

Abstract. Clustering is one of the challenging problems in machine learning. Adopting clustering methods for the picking of microseismic signals has emerged as a new approach. However, due to the low separation of signals generated by microseismic events in real environments and the presence of noise data, existing clustering methods often struggle to ...
