Abstract: The present invention discloses a coal mine multi-disaster fusion early warning method and system, applicable in coal mine safety disaster analysis. First, it builds a model and relationship network among multi-disaster early warning entities, updating the network by specific rules. A trend prediction model using an LSTM artificial neural network is then developed for monitoring object trends, along with natural fission analysis rules. Next, a method for identifying anomalies in single disaster events is established through a disaster index prediction and early warning system. Upon detecting an anomaly in an early warning index, other disaster indexes are assessed using a depth-first traversal algorithm and natural fission rules, facilitating targeted forecasting. This invention builds a predictive relationship chain among early warning indexes through correlation analysis, providing advantages in multi-dimensional analysis and advanced trend prediction.

Abstract: The present invention discloses a mine disaster tracing method based on a knowledge graph, applied in coal mine safety. First, a mine disaster-related knowledge graph is built, involving three main steps: constructing a conceptual model, extracting entities from relational databases and geological maps, and establishing entity relationships based on location and process logic. Next, characteristic indexes and transmission rules for entity objects are set, categorizing entities into four types: discrete reporting, continuous monitoring, geological structure, and geological continuity. When an early warning occurs, disaster tracing is performed using the entity transmission rules and a graph traversal algorithm, identifying direct and root causes. This invention offers systematic and timely disaster tracing by utilizing a specialized knowledge graph and graph algorithms.
