Research on comprehensive gas risk evaluation in coal mine based on cloud model

本文针对煤矿矿井内各类危险源的不确定性特点,利用模糊性和随机性相结合的云模型对瓦斯风险评价指标进行表示.采用基于云模型的煤矿矿井瓦斯风险综合评价方法进行研究,将定性瓦斯风险评价指标和定量瓦斯风险评价指标进行量化和规范化计算.同时,建立了云模型的多层次的煤矿矿井瓦斯风险综合评价指标体系结构,并将其转换成基于云模型的煤矿矿井瓦斯风险综合评价.此外,还根据云重心推理方法,引入基于云模型的煤矿矿井瓦斯风险综合评价方法.

In the present work,the gas risk evaluation is indexed by cloud model with fuzzy and random combination towards the uncertainty of various risk sources in coal mine.Then the qualitative and quantitative gas risk evaluation indices is quantified and subjected to standardized calculation by the above cloud model.Meanwhile,the index system of multi-level gas risk evaluation of coal mine is established and converted into comprehensive gas risk evaluation of coal mine upon the cloud model.In addition,according to the cloud gravity center method of reasoning,comprehensive gas risk evaluation method of coal mine gas is introduced through the cloud model.
