摘要
针对瓦斯突出矿井难以做到对其矿井瓦斯防治系统安全状态进行客观、精准评价的问题。本文首先对矿井瓦斯防治系统安全状态影响因素进行了分析,在此基础上,构建了矿井瓦斯防治系统安全状态评价体系。其次,基于层次分析法,并结合粒子群优化算法PSO对判断矩阵进行优化、修正,在降低主观影响的基础上计算得到评价体系各指标权重。最后,基于云理论与二级指标权重、一级指标权重计算得出总指标的云数字特征,在matlab中运用正向云发生器生成评价指标的标准云模型。并以贵州省某典型瓦斯突出矿井为研究对象,结合该矿现场的实际调研情况,得出矿井瓦斯防治系统安全状态综合判别评价标准指标云,并对该矿瓦斯防治系统安全状态做出了准确评价并提出了相应的整改措施。研究成果对瓦斯突出矿井瓦斯防治系统安全状态的客观精准评价、煤矿安全生产有着重要意义。
It is difficult to objectively and accurately evaluate the safety status of gas prevention and control systems in gas outburst mines.This article first analyzes the factors affecting the safety status of the mine gas prevention and control system,and based on this,constructs a safety status evaluation system for the mine gas prevention and control system.Secondly,based on the Analytic Hierarchy Process and combined with the Particle Swarm Optimization(PSO)algorithm,the judgment matrix is optimized and modified,and the weights of each indicator in the evaluation system are calculated on the basis of reducing subjective influence.Finally,based on cloud theory and the weights of secondary and primary indicators,the cloud digital features of the total indicator are calculated,and a standard cloud model for evaluation indicators is generated using a forward cloud generator in Matlab.And taking a typical gas outburst mine in Guizhou Province as the research object,combined with the actual investigation situation of the mine site,the comprehensive discrimination and evaluation standard index cloud of the safety status of the mine gas prevention and control system was obtained,and the accurate evaluation of the safety status of the mine gas prevention and control system was made,and corresponding rectification measures were proposed.The research results have important significance for the objective and accurate evaluation of the safety status of gas prevention and control systems in gas outburst mines and for coal mine safety production.
