The embodiment of the invention discloses a mine pressure prediction method and device and electronic equipment, relates to the field of coal mining, and can improve the precision of mine pressure prediction. The method comprises the following steps: acquiring mine pressure observation data of each hydraulic support within a target time period; according to the mine pressure observation data corresponding to all the hydraulic supports, determining sample hydraulic supports, related to the target hydraulic support, in all the hydraulic supports except the target hydraulic support; taking the mine pressure observation data of the target hydraulic support and the sample hydraulic support in the first time period as input variables, taking the mine pressure observation data of the target hydraulic support at the first moment as output variables, and establishing a mine pressure prediction model of the target hydraulic support through a deep learning model; and inputting the mine pressure observation data of the target hydraulic support and the sample hydraulic support in the second time period into a mine pressure prediction model, so that the mine pressure prediction model outputs themine pressure prediction data of the target hydraulic support at the second moment. The invention is suitable for predicting the mine pressure of the fully mechanized coal mining face.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a mine pressure prediction method, device and electronic equipment. Background technique [0002] In the field of coal mining, the hydraulic support is the main support equipment to maintain the stability of the surrounding rock of the fully mechanized mining face. The fracture characteristics of the overlying strata, so the effective prediction of mine pressure can be used as a key part of the study of support quality and overlying strata characteristics. Coal mine safety production is of great significance. [0003] At present, the mine pressure prediction methods of hydraulic supports in fully mechanized mining face are roughly divided into three categories: one is based on non-deterministic mathematical methods such as statistics and fuzzy mathematics; the other is based on mine pressure theory to determine the roof structure and explore its physical and mechanical laws....

Problems solved by technology

[0004] However, whether traditional methods or intelligent technologies are used to predict the mine pressure of hydraulic supports in advance, only the time correlation of the mine pressure of the target hydraulic support is considered, that is, the partial correlation and autocorrelation analysis methods are used to predict the mine pressure of the target hydraulic support. However, with the improvement of prediction accuracy requirements, the current mine pressure prediction method can no longer meet the prediction accuracy requirements
