Methods and systems for early automatic detection and alarm of coal mine collapse

Abstract

This invention relates to the field of mining engineering technology and provides a method and system for early automatic detection and alarm of coal mine collapses. The method includes: collecting dripping audio, instantaneous flow rate, cumulative water volume, and collection time from various seepage points in the mine; analyzing the temporal linkage relationship of the data to construct a water vein network topology diagram representing the connectivity of underground fissures; calculating the topological centrality and data uncertainty scores of nodes to determine excitation points; sending commands to the excitation points to trigger active hydraulic disturbance tests and recording response data; optimizing the topology diagram using the response data; and generating an early warning when a new directed edge appears or the weight of an existing edge changes abruptly, based on the optimized topology diagram and real-time data monitoring of topological evolution. This invention, through active exploration and dynamic optimization, accurately captures early fissure changes in collapses, improves the timeliness and reliability of early warnings, and is applicable to early detection of coal mine collapses.
