Working face weighting prediction method based on mine pressure big data construction

The invention relates to a working face weighting prediction method based on mine pressure big data construction. The method comprises the steps of obtaining historical mine pressure data; training the GM grey prediction model based on historical mine pressure data to obtain a trained model; the GM grey prediction model is a multivariable grey model MGM (1, n), and n is the number of variables; and inputting the mine pressure data at the current moment into the trained model to obtain the mine pressure data at the future moment. According to the method, links of mine pressure data acquisition, analysis, prediction, early warning and the like are combined to form an organic whole of working face mine pressure historical data analysis, subsequent weighting rule prediction and construction of an early warning mechanism to guide multi-link mutual matching of production operation; according to the application, the defects of low mine pressure monitoring data acquisition efficiency, poor timeliness, time and labor
