Microseismic activity and subsurface structural characteristic of the Laohutai coal mine in Northeast China based on a linear dense seismic array
Published 2025-04-01“…However, due to the limitations of the seismic stations in the Laohutai coal mine area, the characteristics of the complex microseismic activity and subsurface structure remain debated and poorly understood. In this study, we deployed a new linear dense seismic array in the Laohutai coal mine, and detected 324 new microseismic events by applying the Match and Locate method. …”
