【摘要】 在全面分析回采工作系统结构的基础上，给出了随机可靠度、模糊可靠度和模糊随机可靠度的定义，提出了生产子系统、环境子系统和实施子系统的模糊随机可靠度的计算方法，建立了回采工作系统模糊随机可靠性分析的数学模型。经在实践中检验，证明所提出的方法和数学模型是正确有效的。更多还原

【Abstract】 On the basis of overall review of the structure of mining system, the definitions of random reliability, fuzzy reliability, fuzzy random reliability are given. The methods for fuzzy random reliability degree of a production subsystem, environment subsystem, and management subsystem are proposed. A mathematic model for studying fuzzy random reliability of a mining system is established. The methods and model are proved to be correct and effective by the mines.更多还原
