| 中文摘要: |
| 针对煤与瓦斯突出存在诸多不确定影响因素的特点,在研究煤与瓦斯突出机理和广义回归神经网络的基础上,建立了煤与瓦斯突出的广义回归神经网络预测模型,提出了广义回归神经网络中的光滑因子优化选择算法,以提高模型预测精度.通过应用实例验证,预测结果精度高,与实际情况相吻合.研究结果证明了该方法的合理性和可行性,对煤矿提高煤与瓦斯突出区域的预测能力具有较大的参考意义. |
| 英文摘要: |
| According to the fact that the characteristics of coal and gas outburst exist many uncertain influencing factors, and studying the theory of the coal and gas outburst and set pair analysis, this paper built the regional forecasting model of generalized regression neural network in coal and gas outburst, and put forward the optimization selection algorithm of smoothing factor in the GRNN to raise the precision of forecasting. By proving the application examples, the results had higher precision and were fit to the actual situation. The studying results proved the rationality and feasibility of this method, and it would be more guiding significance for raising the ability of regional forecasting of coal and gas outburst. |
