High-accuracy real-time microseismic analysis platform : case study based on the super-sauze mud-based landslide [PDF]

, 2020
Understanding the evolution of landslide and other subsurface processes via microseismic monitoring and analysis is of paramount importance in predicting or even avoiding an imminent slope failure (via an early warning system).

Multicomponent microseismic data denoising by 3D shearlet transform [PDF]

, 2018
The low-magnitude microseismic signals generated by fracture initiation are generally buried in strong background noise, which complicates their interpretation. Thus, noise suppression is a significant step. We have developed an effective multicomponent,

A method for predicting the time series of microseismic events in coal mines based on modal decomposition and deep learning

Meitan xuebao
Microseismic monitoring data plays a crucial role in predicting and warning dynamic hazards such as coal mine rockburst. Utilizing historical microseismic monitoring data to forecast the evolution characteristics of future microseismic events is an ...

Experimental Study on Calibration of Amplitude-Frequency Measurement Deviation for Microseismic Sensors in Coal Mines

Sensors, 2023
Microseismic monitoring systems (MMS) have become increasingly crucial in detecting tremors in coal mining. Microseismic sensors (MS), integral components of MMS, profoundly influence positioning accuracy and energy calculations. Hence, calibrating these

Inverting Injection-Induced Microseismic Monitoring Data with Coupled Flow and Geomechanical Models: Application to CO2 Injection [PDF]

, 2018
High pressure fluid injection into geologic formations can trigger rock deformation and failure and lead to microseismic events. Injection induced seismicity has been proposed as a monitoring technique that can be used to constrain the description of ...

Microseismicity data for hydrofracture experiment

, 2020
Microseismicity locations in a local coordinate system in the plane of the fracture. Each of the files VascoEtAl_JGR_2020.*minutes.dat represents the seismicity during a 10 minute increment measured from the start of injection. The file VascoEtAl_JGR_2012.times.moments.xy contains the event moment magnitudes as a function of time since the start of ...

Real time identification of microseismic events based on ridge regression improved normative variable analysis

Gong-kuang zidonghua
The identification of microseismic events is the foundation of microseismic monitoring in coal mines. Most existing microseismic monitoring technologies are developed based on the variation law of single physical quantities, which can easily lead to ...
