摘 要:为更加精确地预测煤体瓦斯渗透率,进而保障煤矿安全生产,构建基于改进麻雀搜索算法(ISSA)优化反向传播神经网络(BPNN)的煤体瓦斯渗透率预测模型。首先,通过引入Sine混沌映射和高斯变异改进麻雀搜索算法(SSA),以增强其全局搜索能力和局部寻优精度,从而优化BPNN的权值和阈值配置;然后,通过皮尔逊相关系数矩阵和核主成分分析(KPCA)处理瓦斯渗透率影响因素的数据,以提高模型的计算效率和准确性,并以累积方差达88.59%的3个主成分提取为模型输入,渗透率作为输出进行试验;最后,将该模型应用于山西某煤矿进行实例验证。结果表明:ISSA-BPNN在平均绝对误差(MAE)、平均绝对百分比误差(MAPE)、均方根误差(RMSE)和决定系数R^(2)等4个指标上优于粒子群算法(PSO)优化BPNN、PSO优化支持向量机(PSO-SVM)、PSO优化最小二乘支持向量机(LSSVM)及SSA优化BPNN(SSA-BPNN)模型,且相较于其他模型在测试样本中的平均绝对误差(MAE)分别降低0.0327、0.022、0.0179、0.0182;MAPE分别降低5.15%、3.14%、2.76%、2.36%;RMSE分别降低0.0316、0.0279、0.0188、0.0222;R^(2)分别提高0.0775、0.0658、0.0401、0.0493;实例验证表明模型可靠性和稳定性较高。In order to predict coal gas permeability more accurately and ensure coal mine safety production,a prediction model of coal gas permeability based on ISSA-optimized BPNN was constructed.Firstly,the sparrow search algorithm(SSA)was improved by introducing Sine chaotic mapping and Gaussian mutation to enhance its global search capability and local optimization accuracy,thereby optimizing the weight and threshold configuration of BPNN.Secondly,the data on the factors affecting gas permeability were processed using Pearson correlation coefficient matrix and kernel principal component analysis(KPCA)to improve the computational efficiency and accuracy of the model.Three principal components with a cumulative variance of 88.59%were extracted as model inputs,and permeability was used as the output for the experiment.Finally,the model was applied to a coal mine in Shanxi for case verification.The experimental results show that ISSA-BPNN outperforms PSO-BPNN,PSO-SVM,PSO-LSSVM,and SSA-BPNN models in four indicators:mean absolute error(MAE),mean absolute percentage error(MAPE),root mean square error(RMSE),root mean square error(RMSE),and coefficient of determination(R^(2)).Compared with other models,ISSA-BPNN has reduced MAE by 0.0327,0.022,0.0179,and 0.0182 in the test samples,respectively.MAPE decreases by 5.15%,3.14%,2.76%,and 2.36%respectively.RMSE decreases by 0.0316,0.0279,0.0188,and 0.0222 respectively.R^(2)increases by 0.0775,0.0658,0.0401,and 0.0493,respectively.Finally,the case verification shows that its reliability and stability are high in practical applications.
