基于模糊判定理论的煤矿工作面顶板状态灾变预警的研究

Disaster Warning of Roof on Working Face Based on Fuzzy Theory

针对反应煤矿工作面顶板安全状态的各因素的变化,以及其各个因素之间的关系,采用模糊判定理论,构建工作面顶板、巷道围岩安全状态、各影响因素之间的隶属度函数关系,进而建立顶板安全状态与影响因素间的数学模型,分析判定顶板安全状态和预警级别[1]。帮助技术人员及时了解顶板状态和采取有效措施,降低矿井顶板事故的发生。

To find out the variation and relationship of factors of roof safety on working face, fuzzy judgment theory was used to establish a membership function and a mathematical model between the safety and the influential factors for the roof and surrounding rock in roadways in order to judge the safety situation and alarm level. The study could help that technical staffs know the roof situation and take measures in time, which could effectively reduce the roof accident rate in mines.
