Researchers Develop AI Model for Early Warning of Rock Burst in Coal Mines

Strategic Insights -

Researchers from Xi'an University of Science and Technology have developed a time risk level early warning model that can predict and prevent rock bursts in coal mines. According to the study, the model combines Bayesian optimization algorithm with long-term and short-term memory network, allowing it to accurately warn most "strong" level events with an accuracy of 84.8%. The model has been tested in engineering practice and has shown promising results, providing technical support for rock burst mine monitoring and disaster prevention and control.
