    基于GRA-RBF神经网络模型的煤矿安全风险预控管理安全风险评价研究

    Safety risk assessment in coal mine safety risk pre control management based on GRA-RBF neural network model

    • 摘要: 煤矿安全风险预控管理因素复杂,在实际评价过程中,层级混乱导致安全风险评价输出的MAPE数值较小,使得煤矿安全风险评价结果缺乏准确性。针对煤矿安全风险预控管理问题,提出了一种基于灰色关联分析(GRA)与径向基函数(RBF)神经网络模型的安全风险评价方法。首先,融合大量煤矿环境数据,构建多层级安全风险评价体系,全面考量各层次及要素对安全风险的影响。其次,通过GRA算法,依据安全风险紧急程度确定关键预控管理指标,确保评价的精准性与针对性。最后,利用RBF神经网络的强大非线性映射能力,特别是其径向基函数对高权重安全风险指标的精细处理,并定义神经网络每层拓扑结构处理过程,实现评价结果的输出。为验证该方法的有效性,本文准备了多样化的安全风险数据集,并进行降维处理以生成不同数量的安全指标,匹配不同的聚类参数。在对比实验中,将新方法与两种已成熟应用的安全风险评价方法并行测试,以MAPE作为核心评价指标。研究结果显示,本文所设计的基于GRA-RBF神经网络模型的安全风险评价方法输出的MAPE数值显著提升,表明其能够更准确地预测高风险安全评价指标,对于煤矿安全风险预控管理工作提供了相应的风险评价标准,在一定程度上保证了煤矿安全工作的顺利开展,能够为煤矿安全风险预控管理提供强有力的技术支持和决策依据。

       

      Abstract: The factors of coal mine safety risk pre control management are complex. In the actual evaluation process, the chaotic hierarchy results in a small MAPE value output from safety risk assessment, which leads to a lack of accuracy in the results of coal mine safety risk assessment. This paper proposes a safety risk assessment method based on Grey Relational Analysis (GRA) and Radial Basis Function (RBF) neural network models for coal mine safety risk pre control management. Firstly, integrating a large amount of coal mine environmental data, constructing a multi-level safety risk assessment system, comprehensively considering the impact of each level and element on safety risks. Then, using the GRA algorithm, key pre control management indicators are determined based on the urgency of safety risks, ensuring the accuracy and pertinence of the evaluation. Finally, utilizing the powerful nonlinear mapping ability of RBF neural network, especially its radial basis function for fine processing of high weight safety risk indicators, and defining the topological structure processing process of each layer of the neural network, the evaluation results are ultimately output. To verify the effectiveness of this method, this study prepared a diverse set of safety risk datasets and performed dimensionality reduction to generate different numbers of safety indicators and match them with different clustering parameters. In the comparative experiment, the new method is tested in parallel with two mature safety risk assessment methods, with MAPE as the core evaluation indicator. The research results show that the MAPE values output by the safety risk assessment method based on the GRA-RBF neural network model designed are significantly improved, indicating that it can more accurately predict high-risk safety evaluation indicators, provide corresponding risk evaluation standards for coal mine safety risk pre control management, and to a certain extent ensure the smooth progress of coal mine safety work. It can provide strong technical support and decision-making basis for coal mine safety risk pre control management.
