矿井通风是矿山生产的一个重要环节，通风安全工作的好坏直接关系到矿山的安全生产和经济效益。目前我国矿井通风安全工作得到了很大的发展，但是还存在着一个重要的问题就是缺乏必要的准确的通风数据。 本文在详细分析现有矿井通风安全计算及相应软件的研究现状的基础上，根据矿井的实际情况和需要，针对现有通风软件的不足，提出了矿井通风基础数据计算的研究。本文的研究目标是利用矿井通风报表中的实测数据和通风技术人员的经验数据及巷道参数信息，在图论及通风网络中风流的基本定律的基础上，应用最优化方法的知识，得到矿井准确的通风基础数据。 本文利用矿井的风量数据较容易获得这一条件，提出了由分支的风量来求解分支风阻的方法。本论文研究的矿井通风数据获取方法，能够充分利用日常通风管理中的通风数据信息，通过计算得到矿井全部巷道的风阻和风量数据，为风网解算和矿井安全管理提供完整的基础数据，减轻了矿井通风安全管理和技术工作人员的工作量，而且精度也比较高，为矿井通风计算和分析软件的应用打下了很好的基础，在复杂矿井通风系统中有着重要意义。

Mine ventilation is an important part of the mine production.Ventilation safety is directly related to the quality of mine safety in production and economic benefits. At present, Mine ventilation safety has a great development,but there are still an important issue of mine ventilation safety that is the lack of necessary and accurate ventilation data. In this paper, based on the research of detailed analysis of the existing mine ventilation calculation and the corresponding security software, according to the actual situation of mine and the scarcity of existing ventilation software,proposed the research of mine ventilation foundation data computation. the goal of this research is that appling the knowledge of optimization technique to get complete and accurate mine ventilation foundation data.It based on graph theory and the basic law of airflow in the ventilation network,and used the measured data in ventilation report forms, experience data of Technical staff and parameters information of mine roadway. Because the air quantity data of mine is easier to acquire , I raise the method of solving ventilation resistance by air quantity. this methods can take full advantage of the ventilation data of mine daily management. it can calculate the ventilation resistance and air quantity data of mine roadway and provide a complete foundation data for the ventilation network calculation and the mine safety management . This method not only reduce the workload of mine ventilation safety Managers, but also improve the accuracy of ventilation data. It can lay a good foundation for the calculation and analysis of mine ventilation software, and has an important significance in a complex mine ventilation system.
