矿井通风是保障矿井矿井安全的最主要技术手段之一。在矿井生产过程中，必须源源不断的将地面空气输送到井下各个作业地点，以供给人员呼吸，并稀释和排除井下各种有毒、有害气体和矿尘，创造良好的矿内工作环境，保障井下作业人员的身体健康和劳动安全。这种利用机械或自然通风为动力，使地面空气进入井下，并在井巷中做定向和定量地流动，最后将污浊空气排出矿井的全过程就称为矿井通风。因此，矿井通风的首要任务就是要保证矿井空气的质量符合要求。
本设计介绍了五沟煤矿基本地质情况，确定通风方式和通风系统，运用AUTOCAD绘制通风系统图和通风网络图，运用MVENT通风网络解算软件计算矿井总阻力，进行风量分配，使各个用风点都得到合理的风量。根据矿井总阻力和总风量选择合理的风机和电机，使其满足安全、经济、可靠的要求。
设计得出五沟煤矿通风系统为中央并列式，风机工作方式为抽出式，工作面通风系统为U型，随着工作面的不断推进，风路不断增长，矿井总阻力逐渐增大，需风量也显著增加，计算得出通风容易时期和困难时期的需风量和总阻力。最后提出通风安全措施，保证矿井正常生产和人员安全。
Mine mine mine ventilation is to protect the safety of one of the most important technical means. In the mine production process, it is essential to the air stream will be transported to the various underground sites in order to supply staff to breathe, and dilution and removal of underground toxic, harmful gases and mineral dust, mine to create a good working environment, the protection of underground operating staff's health and labor safety. This use of mechanical or natural ventilation as a driving force, so that the air entering the mine, and mine do quantitative orientation and movement of polluted air from the end of the whole process of mine called mine ventilation. Therefore,
Mine ventilation of the primary task is to ensure the quality of mine air to meet the requirements.
Designed to introduce the five basic geological conditions of coal mine to determine the mode of ventilation and ventilation systems, ventilation systems using AUTOCAD drawing network maps and ventilation, the use of the ventilation network solution MVENT software calculated the total resistance to the mine to carry out the distribution of air flow so that each use of the wind points have been a reasonable amount of wind. According to mine the total resistance and a reasonable choice of the total air volume of fan and motor to meet the security, economic, reliable requirements.
Designed to draw the five coal mine ventilation system for the central parallel, fan out of work for style, face ventilation systems for the U-type, with the continuous advance of face, the way the wind is growing, the total shaft resistance increases, the need Wind was also a significant increase in ventilation easily calculated and difficult period of time required and the total resistance to air flow. Finally, ventilation measures, to ensure normal production and personnel mine safety.

Pick
Coal mine ventilation system is the guarantee of the main technical means to safety. In mine production process, must continuously be ground to air transport underground workplace, with each breath, and supplies dilution and exclude poisonous and harmful gases in all kinds of dust, and to create a good environment to work in the mines, safeguard the physical health of workers and labor safety. The use of natural ventilation powered mechanical or underground air into the ground, and do in shaft and quantitatively, air pollution will flow out of mine ventilation system is called the process. Therefore, mine ventilation priority is to ensure the quality of the air with mine.
This design is introduced the basic geology condition, ditch mine ventilation and determine the ventilation system, using AUTOCAD drawing ventilation system graph and ventilation network diagram, using MVENT ventilation network calculation software calculating total resistance, mine air distribution, make each point in the reasonable volume. According to mine total resistance and total air blower and the rational choice, the economic, reliability and safety requirements.
Designed for coal mine ventilation system five ditch central paratactic type, fan work method for drawer-type, ventilation system for U, along with the advancement of wind and growing mines, total resistance increase gradually, should also increased significantly, and air ventilation easy calculated period and difficult period of total resistance and need air. Finally, ensure mine ventilation safety measures and normal production safety.
