摘要
综合不同水位下,不同身高特征对矿工在矿井突水时期逃生速度的影响,分析了身高不同的矿工在不同水位下的行走速度与水位之间的函数关系,提出并建立了相应的关系函数模型——阻滞型水中逃生速度曲线数学模型,并基于该模型计算影响矿工逃生速度的影响系数;同时为了动态描述巷道的安全通行能力,根据模糊评价原理,引入了相应的安全系数;结合巷道实际道路特征,优化了矿井水灾逃生数学模型。优化后的数学模型不仅可以针对不同身高特征的矿工设计最优逃生路径,也可以在人员较多时采用平均身高设计最优逃生路径。
This paper summarizes the effect of different height characteristics on the escape speed of miners under different water level in the period of mine water flood and analyzes the functional relationship between the walking speed and water level of miners with different height at different water level, proposes and sets up the corresponding relation function model which is the mathematical model of retarding speed curve in water, and calculates the influence coefficient of miners＇ escape velocity based on this model. In order to describe the safety capacity of roadway dynamically, according to the fuzzy evaluation principle, the corresponding safety factor is introduced. Finally, combining with the actual roadway characteristics, the mathematical model of mine flood escape is optimized. Then, the optimized mathematical model can not only design the optimal escape route for miners with different height characteristics, but also design the optimal escape route with average height when there are more staff.
