Coal mine three-illegal behavior recognition model training method and device and storage medium

The invention provides a coal mine three-violation behavior recognition model training method and device and a storage medium, and the method comprises the steps: obtaining a three-violation behavior sample and a safety behavior sample, the unbalance rate of which is smaller than or equal to a first threshold value, each sample at least comprises the following indexes: personnel educational background, working age limit, health index, operation time, operation place, operation shift, event type and well ascending and descending time, clustering the three-illegal behavior sample and the safety behavior sample to obtain a plurality of candidate clusters, the method comprises the steps of selecting a plurality of candidate clusters, screening a target cluster of which the number of three-illegal behavior samples is greater than a second threshold value from the plurality of candidate clusters, performing oversampling on the target cluster by adopting an SMOTE algorithm to obtain a balanced sample data set, and t
