Description

Technical Field

[0001] The present application relates to the field of mine safety monitoring and early warning technology, and in particular to an online monitoring and early warning system for mine rock burst. Background Art

[0002] Rock burst occurs when the elastic deformation energy accumulated in the rock mass is suddenly and violently released under certain conditions, causing the coal and rock to burst and be ejected. Rock burst often leads to roof collapse, damage to mines and tunnels, resulting in casualties, equipment damage, and environmental pollution, seriously impacting coal mine production and personnel.

[0003] Currently, mine rock burst monitoring relies primarily on regular manual inspections, a method with limited real-time performance and difficulty identifying potential risks. While some mines have experimented with automated monitoring equipment, these devices have limited functionality and lack comprehensive analysis and early warning capabilities. Furthermore, existing automated monitoring equipment suffers from slow data processing and early warning response times, resulting in low accuracy and difficulty meeting the practical needs of modern mine safety production.

[0004] Therefore, how to improve the real-time performance of mine rock burst monitoring and the accuracy of early warning and reduce the safety risks in mine operations has become a technical problem that needs to be solved urgently in this field. Utility Model Content
