瓦斯爆炸是威胁煤矿安全开采的重大灾害之一.实验室进行管道模拟瓦斯爆炸实验是研究瓦斯爆炸特性的有效方法.针对瓦斯爆炸实验进行之前实验气体载气过程中出现的载气时间不明确,载气量模糊等问题,使用压差流量计算方法建立相关数学模型,并利用计算机编程语言Visual Basic进行计算机编程实现迭代计算.通过计算发现载气过程相当短暂,并且载气过程中管道内的压力增加与载气时间呈二次方关系.
Gas explosion is one of the major hazards that threaten the safe mining of coal mines.It is an effective method to study the characteristics of gas explosion in the experiment of pipeline simulation gas explosion in laboratory.It is not clear for the carrier gas to appear in the experimental gas before gas explosion experiment, The carrier gas quantity is fuzzy and so on, the mathematical model is established by using the differential pressure flow calculation method, and the computer programming language is used to realize iterative calculation by using computer programming language Visual Basic.It is found through calculation that the process of carrier gas is rather short and the pressure in the pipeline is increased And the carrier gas showed a quadratic relationship.
