Abstract
Description
Technical Field
[0001] This invention relates to the field of evaluation and real-time optimization system technology, and in particular to an intelligent evaluation and real-time optimization system for the prevention and control of dynamic disasters in deep fluidized bed mining. Background Technology
[0002] With the continuous growth of global demand for mineral resources and the increasing depletion of shallow resources, mineral resource mining inevitably moves towards deeper areas. Deep mining faces an extremely complex and harsh geomechanical environment, characterized by "three highs and one disturbance" (high ground pressure, high ground temperature, high osmotic pressure, and strong mining disturbance). Under such conditions, traditional mining methods are highly susceptible to triggering a series of dynamic disasters, such as rock bursts (rock bursts), large-scale roof pressure, pillar instability, and sudden collapse of goaf areas, which seriously threaten mine safety and the lives of personnel.
[0003] Fluidized bed mining, as a highly efficient mining technology, is being used more and more widely in deep mines. By converting ore or media into a fluidized state for transportation and recycling, mining efficiency can be improved and energy consumption reduced. However, it also introduces new dynamic disaster risks, such as fluidized medium instability, pipeline blockage, and pressure surges, which require real-time monitoring and optimized control.
[0004] Currently, the evaluation of the effectiveness of dynamic disaster prevention and control in fluidized mining is mostly still in the initial stage of "post-event statistics, static assessment, and experience judgment," which has obvious shortcomings. Existing methods often focus on data analysis from a single source, such as monitoring only microseismic events or measuring only stress changes in a certain profile. They lack the fusion analysis of multi-source information (stress, microseismic events, acoustic emission, displacement, etc.), making it difficult to comprehensively and accurately reflect the overall stability of the fluidized medium and surrounding rock system. There is a lack of correlation analysis between various indicators, making it impossible to reveal the multi-faceted precursory characteristics and internal mechanisms of disaster formation. Summary of the Invention
[0005] Given that the existing methods often focus on single-source data analysis, such as monitoring only microseismic events or measuring only stress changes in a certain profile, and lack the fusion analysis of multi-source information (stress, microseismic events, acoustic emission, displacement, etc.), it is difficult to comprehensively and accurately reflect the overall stability state of the fluidized medium and surrounding rock system. Furthermore, there is a lack of correlation analysis between various indicators, which fails to reveal the multi-faceted precursory characteristics and intrinsic mechanisms of disaster formation. Therefore, this invention is proposed.

[0119] Example 1
[0120] Step 1: System Deployment and Data Acquisition
[0121] A monitoring network was deployed in the -850m level stope: 12 stress sensors were installed in the fluidized medium, 8 microseismic monitoring instruments were installed on the roof and sidewalls, 6 acoustic emission probes were deployed in key areas, and 15 displacement monitoring points were set up around the roadway.
