摘要
为了提高矿井通风系统的稳定性,合理预测风量以及优选风量调节分支,提出了有效度矩阵分析矿井通风系统稳定性的方法。通过理论分析以及数学计算的方法建立有效度的数学模型,对矿井通风系统的有效度进行研究,选取实例进行算例分析,可得到矿井通风系统的稳定性可由有效度矩阵进行判定。研究表明:有效度是衡量矿井通风可靠程度的重要指标,是矿井通风系统的固有属性,正常状态和失效状态是衡量有效度的关键因素。
In order to improve stability of coal mine system,predict air quantity and optimize air quantity regulating branches reasonably,in this paper,method of validity matrix analyzing coal ventilation system stability is raised,mathematical model of air quantity optimization adjustment is established by theory analysis and mathematical calculation,validity of coal mine ventilation system is studied,example chosen was analyzed practically,validity of whole coal mine ventilation system was judged by result of validity matrix analyzed.The result shows that validity is significant indicator to measure mine ventilation system reliability,is the intrinsic properties of ventilation network structure,average time of normal ventilation and average time of failure ventilation is the critical factors of measuring validity.
