基于Rough Set的矿区REES系统中的瓦斯事故分析

Gas Accident Analysis in Diggings REES System Based on Rough Set Theory

瓦斯事故是煤矿经常发生的事故,在矿区REES系统中应对其有准确的分析与预测,采用了Rough Set理论对矿区REES系统中事故分析进行了建模,给出了分析步骤与流程,然后利用作业评价法评价矿井中煤与瓦斯突出分类等级,最后利用Rough Set理论建立煤与瓦斯的决策表,求得其约减,提取决策规则,对规则进行了分析,用于指导煤矿开采。

The gas accident is the accident which is frequently occurred in the colliery.In order to exactly analyze and predict the safety of the gas accident in the diggings REES system,firstly the rough set theory is used to model the accident analysis in the REES system,and the analysis process and steps are given out.Then the coal and gas levels are classified using the task estimating method.Finally the coal and gas tables are founded and then reduced,and the decision-making rules are obtained and analyzed to guide the coal mine exploitation.
