Picking the first arrival of microseismic signals, quickly and accurately, is the key for real-time
data processing of microseismic monitoring. The traditional method cannot meet the high …

Fault-excited repetitive transients are apt to be submerged in unavoidable noise. Till now,
most vibration-based diagnostic methods just reject the noise outside the optimal frequency …

Microseismic source location is a fundamental research interest in real-time microseismic
monitoring and hazard risk assessment, and it provides the basis for determining the fracture …

Microseismic sensing taking advantage of sensors can remotely monitor seismic activities
and evaluate seismic hazard. Compared with experts' seismic event clusters, clustering …

Microseismic (MS) source location is a fundamental and critical task in mine MS monitoring.
The traditional ray tracing-based location method can be easily affected by many factors …

Microseismic source location is crucial for the early warning of rockburst risks. However, the
conventional methods face challenges in terms of the microseismic wave velocity and arrival …

Microseismic (MS) source location is a critical technology in MS monitoring. Traditionally, P-
wave or S-wave travel time-based ray-tracing algorithms are adopted for a mine MS event …

The onset times of acoustic signals with spikes, heavy bodies and unclear takeoffs are
difficult to be picked accurately by the automatic method at present. To deal with this …

The acoustic emission (AE) technique has been widely used in studying the cracking and
frictional behavior of rocks in laboratory rock mechanics tests. Picking P-wave arrivals of AE …
