目前，对工作面顶板灾害进行预测、预警的相关研究成果较少，并且主要集中于

At present, there are few related research results on the prediction and early warning of roof disasters in working faces, and they mainly focus on the study of the evolution characteristics of the stress field and the fracture structure of the roof rock formations [34-36], and use data models to predict roof disasters There are fewer research results, and the relevant algorithm results that can predict the load of the hydraulic support for one fracture cycle of the roof have not been retrieved.

At present, there are fewer research results on the prediction and early warning of the top plate disaster, and mainly focus on the study of the stress field evolution characteristics and fracture structure characteristics of the top plate rock formation.

At present, there are few related research results on prediction and early warning of roof disaster in working face, and mainly focus on the stress field evolution characteristics and fracture structure characteristics of roof strata [34-36]. The research results of roof disaster prediction using data model are less, and the phase that can realize the prediction of hydraulic support load for a roof fracture cycle has not been retrieved Results of the algorithm.<br>
