Abstract Characterizing seismic moment tensors of small‐ to moderate‐magnitude earthquakes (i.e., 2.5< M <4.0) still represents a challenge in observational seismology. To address this problem, inversion methods based on fitting the first‐motion polarity and/or amplitude ratios recorded waves have been designed, and where possible, full waveform inversions were also used. The that include combination subsets data are desirable, but weighting each subset is typically treated an ad hoc...
We observed high-quality waves from a repeatable airgun seismic source recorded by linear ultra-dense array across the Xiliushui fault zone, one of inactive faults in Qilian Mountain, on northeastern margin Tibetan Plateau, China. used Snell’s law ray propagation to determine simplified ambient velocity model. Based flexible and precise spectral element method, we computed broadband synthetic seismograms for shallow low-velocity zone (FZ) model direct P-wave travel time delay incident angle...
The layout of acoustic emission sensors plays a critical role in non-destructive structural testing. This study proposes grid-based optimization method focused on multi-source location results, contrast to traditional sensor methods that construct correlation matrix based and one source location. Based the seismic travel-time theory, proposed establishes objective function minimum differences, which is solved through particle swarm (PSO) algorithm. Furthermore, accuracy across various...

Rapid and accurate assessment of fracture permeability is critical for subsurface resource energy development as well rock engineering stability. Fracture deviates from the classical cubic law under effect roughness, geological stress, mining-induced stress. Conventional laboratory tests numerical simulations are commonly costly time-consuming, whereas use a connectivity metric based on percolation theory can quickly predict permeability, but with relatively low accuracy. For this reason, we...
Signal denoising is one of the most important issues in signal processing, and various techniques have been proposed to address this issue. A combined method involving wavelet decomposition multiscale principal component analysis (MSPCA) has exhibits a strong performance. This technique takes advantage several signals that similar noises conduct denoising; however, are usually quite different between signals, limited adaptive abilities for complex signals. To issue, we propose based on...
Microseismic sensing taking advantage of sensors can remotely monitor seismic activities and evaluate hazard. Compared with experts’ event clusters, clustering algorithms are more objective, they handle many events. Many methods have been proposed for the K-means technique has become most famous one. However, be affected by noise events (large location error events) initial cluster centers. In this paper, a data field-based methodology is seismicity analysis. The application synthetic real...
Microseismic source location is a fundamental research interest in real-time microseismic monitoring and hazard risk assessment, it provides the basis for determining fracture zones calculating seismic parameters of microseismicity (e.g., event magnitude, focal mechanism). In present work, we carefully relocate some earthquakes that occurred Yongshaba mine (China) using shooting 3-D ray-tracing (3D-RT) method based on high-resolution velocity model, which determined by large amount data....

Microseismic (MS) source location is a fundamental and critical task in mine MS monitoring. The traditional ray tracing-based method can be easily affected by many factors, such as multi-ray path effects, waveform focusing defocusing of wavefield propagation, low picking precision seismic phase arrival. By contrast, the Gaussian beam reverse-time migration (GBRTM) effectively correctly model influences multi-path effects complex 3D media, it takes advantages maximum energy point with...
The acoustic emission (AE) b value plays an important role in studying structural damage evolution and disaster precursors. can be obtained from the least square fit between AE event number magnitude (the Gutenberg-Richter relationship), where is generally calculated through maximum amplitude of signal. However, magnitudes amplitudes different signals may quite different, due to influence coupling state sensor specimen (expressed as sensitivity coefficient, Sc). Thus, values a single without...
Drainage tunnel stability is crucial for engineering project safety (e.g., mine and dams), rockfall events water release are key indicators of drainage stability. To address this, we developed a monitoring system to simulate intrusions based on distributed acoustic sensing (DAS), obtained typical characteristics like release. Given the multitude DAS signal feature parameters challenges, such as high-dimensional features impacting classification accuracy machine learning, proposed an...
