This invention discloses a method for predicting the time required for personnel to return to the working face after blasting mining in underground non-
coal mines. It relates to the field of
mine safety prediction technology. First, a
negative feedback neural
network model is established to correlate the personnel
return time with four relevant indicators: roadway,
ventilation duct, explosives, and gas. An initial model of the
negative feedback neural network is configured. Sample data is collected from multiple channels. The weights and biases of the
negative feedback neural network are globally optimized to obtain a prediction model for the personnel
return time after blasting mining within the allowable error range. This prediction model is then trained and tested. Decision-makers use the prediction model to predict the
return time and guide relevant personnel to return to the working face to continue operations. This invention achieves intelligent and accurate prediction of the personnel return time after blasting mining, effectively improving the accuracy and speed of the prediction results, making the predictions more scientific and effective, and enhancing their reliability.
