Early-warning evaluation and warning of rock burst using acoustic emission characteristics of coal sample failure

Meitan kexue jishu, 2023
As the most common dynamic disaster of coal rock in deep coal mining, rock burst seriously affects the safe and efficient mining of coal resources. Accurate and timely to predict the rock burst is the best way to control and prevent it. In order to study

Uncertainties in microseismic event location analysis [PDF]

, 2015
Microseismic monitoring is the observation technique of small earthquakes, called microseismic events, which occur in the ground as a result of human activities or industrial processes such as hydraulic fracturing.

An Enhanced RIME Optimizer with Horizontal and Vertical Crossover for Discriminating Microseismic and Blasting Signals in Deep Mines

Sensors, 2023
Real-time monitoring of rock stability during the mining process is critical. This paper first proposed a RIME algorithm (CCRIME) based on vertical and horizontal crossover search strategies to improve the quality of the solutions obtained by the RIME ...

FractVis: Visualizing Microseismic Events [PDF]

, 2013
We present our efforts of applying information visualization techniques to the domain of microseismic monitoring. Microseismic monitoring is a crucial process for a number of tasks related to oil and gas reservoir development, e.g., optimizing hydraulic fracturing operations and heavy-oil stimulation.

Microseismic clustering degree: concept, algorithm and application of five-dimensional index of microseismic spatiotemporal evolution

Meitan xuebao
Microseismic monitoring has become an important means of mine safety identification and early warning, but the spatiotemporal evolution mechanism based on microseismic and its correlation with rock activity still need to be solved urgently.

Adaptive microseismic noise estimation and denoising [PDF]

, 2016
Microseismic data recorded by surface arrays are often strongly contaminated by unwanted random noise. This background noise makes the detection of small magnitude events difficult.
