摘　　要：顶板压力预测大多都使用1台液压支架的压力数据,缺乏相邻支架的压力相关性,基于相邻多台液压支架信息融合的LSTM-TCN模型预测一支架下一时刻的压力值。实验结果表明,该模型相比LSTM和TCN单支架预测模型,RMSE压力误差分别减小了12.3%和13.4%,MAE压力误差减小了10.3%和26.6%。Most of the top plate pressure prediction uses the pressure data of one hydraulic bracket,and the pressure correlation of adjacent brackets is lacking,and predicts the pressure value of a bracket at the next moment based on the LSTM-TCN model of the information fusion of multiple adjacent hydraulic supports.Experimental results show that compared with LSTM and TCN singlebracket prediction models,the RMSE error value is reduced by 12.3%and 13.4%,the MAE error value is reduced by 10.3%and 26.6%.
