Accurate evaluation of the influence range of borehole hydraulic fracturing (HF) in coal seam is crucial for optimizing the design scheme of HF. In this study, we adopted the microseismic …
We present a new methodology for detection and space–time location of seismic sources based on multiscale, frequency-selective coherence of the wave field recorded by dense …
The ability to detect small microearthquakes and identify their P-and S-phase arrivals is a key issue in hydrofracture downhole monitoring because of the low signal-to-noise ratios …
