Prediction of mine strata behaviors law and main control factors in the fully mechanized caving face of Hujiahe Coal Mine

Gong-kuang zidonghua
Among the existing prediction methods for strata behaviors law in working faces, the methods based on numerical simulation and statistical regression cannot achieve real-time and precise prediction of strata behaviors law in working faces. Deep learning methods have problems such as a large number of hyperparameters that are difficult to set and slow ...
