    • 摘要: 为了对煤巷围岩稳定性进行科学、准确的预测,提出了一种将自适应差分进化算法(JADE)与极限学习(ELM)结合的煤巷围岩稳定性预测新方法。基于ELM训练速度快、泛化能力好和易获取全局最优解的优点,采用JADE优化ELM的输入权值矩阵和隐含层偏差,减少随机性造成的误差,建立JADE-ELM煤巷围岩稳定性预测模型。利用霍州煤矿区煤巷实测数据进行实例分析,并将预测结果与ELM、BP、RBF神经网络比较。结果显示:JADE-ELM模型预测平均精度为97.85%,比ELM、BP、RBF模型分别高出4.05%、17.85%、22.85%,JADE-ELM模型具有更高的预测精度,能够更准确的对煤巷围岩稳定性进行预测。

       

      Abstract: In order to predict the surrounding rock stability in coal roadway scientifically and accurately, a new prediction method combined self-adaptive different evolution (JADE) with extreme learning machine (ELM) was proposed. Considering the advantages of ELM which has quick training speed, good generalization performance and accessing to the global optimal solution easily, JADE is used to optimize the input layer weight matrix and hidden layer bias of ELM so that the random error could be reduced, and the JADE-ELM prediction model is built. Case analysis is made by using measured data of Huozhou Coal Mine area, and the prediction result is compared with ELM, BP and RBF. The results show that the average accuracy of JADE-ELM model is 97.85% which is 4.05%, 17.85% and 22.85% higher than that of ELM, BP and RBF, it proves that the JADE-ELM model has a higher accuracy and can be more accurate to predict the stability of coal roadway.
