Description

Technical Field

[0001] This invention relates to the field of mining area monitoring and early warning technology, and in particular to intelligent mining disaster early warning methods and devices. Background Technology

[0002] With the current high demand for mineral resources and the gradual depletion of domestic mineral reserves and easily mined resources, mines are increasingly turning to the exploitation of deep resources. As mining depth increases, various disasters induced by mining, such as rock bursts, roof falls, and rib collapses, are becoming increasingly prominent, making mine disaster prediction and early warning imperative.

[0003] However, in existing technologies, mine disaster early warning relies on multi-point monitoring on-site, which cannot achieve comprehensive coverage. Since multi-point monitoring data comes from sensors scattered across various monitoring points, this type of data can only reflect the mechanical response state within a small area near the monitoring point and cannot achieve comprehensive coverage. This leads to poor data quality. Furthermore, with the real-time changes in the mine environment, existing monitoring data may be distorted due to rock mass damage, mining disturbances, and environmental factors in the mining area. Therefore, how to provide an intelligent mine disaster early warning method and device is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent method and device for early warning of mine disasters. This invention effectively improves the accuracy and real-time performance of mine disaster prediction and early warning by conducting full-coverage analysis and modeling of the mine and combining numerical simulation analysis.
