The sensor network layout is a key factor affecting the accuracy and stability of the microseismic/acoustic source (MS/AE) location. Based on the arrival-time-difference principle, the hyperbolic/hyperboloidal governing equations for the source locat

Accurate detection and picking of the P-phase onset time in noisy microseismic data from underground mines remains a big challenge. Reliable P-phase onset time picking is necessary for accurate source location needed for planning and rescue operation

The performance of acoustic emission/microseismic (AE/MS) monitoring systems in mines is greatly impacted by background noise interference. Mine trucks/vehicles, fans, blasting and electrical spikes generate noise which negatively affect AE/MS signal

Roof fracture has been a persistent threat to coal mine safety. In this paper, a physical modeling system was established to explore the fracture mechanism of the hard roof. The characteristics of acoustic emission (AE) signals during the process of

The arrival-time-difference approach is the dominant source location approach used in the microseismic source location area. Multiple solutions problem is one of the major concerns in microseismic source location, which is closely related to the micr

A thin and rigid limestone roof and high horizontal stresses in an underground limestone mine have caused severe roof fall problems. To help the mine address these problems, an acoustic emission/microseismic system was installed at the mine. However,

In–seam seismic (ISS) refers to methods which utilise artificially generated channel waves trapped in coal seam to locate geologic disturbances and mine voids. It is one of the basic geophysical methods for underground survey. The advantage of ISS

The application of the acoustic emission (AE) technique has been severely limited during the past several decades due to the difficulties of source location on general shell structures. Two major obstacles are the lack of search algorithms on shell s
