英文摘要：

Natural wind pressure is an important part of mine ventilation power, which is closely related to ventilation sys- tem and ventilation network. With increases in coal production and mining depth, the effect of natural wind pressure on ventila- tion system will be more and more important. In order to efficiently predict and calculate natural wind pressure and analyze its effect on ventilation system, a real-time calculation method of natural wind pressure was put forward. Using fluid statics and thermodynamics combined with ventilation network calculation algorithm, the real- time algorithm of natural wind pressure was obtained. Considering an actual coal mine named Changping mine of Jincheng Anthracite Mining Group, real-time network solu- tion of natural wind pressure in different temperatures and pressures were carried out. The results indicated that the algorithm can be used for ventilation network automatic solution with natural wind pressure and achieving solution results of ventilation network with natural wind pressure efficiently and real-timely, which provides a technical support to ensure the operation of ventilation system stable and reliable.
