山西天地王坡煤矿矿井通风设计 摘要： 关键词：通风设计 通风系统 通风阻力 Abstract :The mine ventilation system direct mainly at the mine of Tiandi Wangpo which located at Shanxi province.The mine which has natural advantages that own the simple geological structure .The mine of Wangpo belongs to the highly gassy mine whose coal seam has no tendency explosion . The problem of the highly gassy can be solved by drawing out methane and ventilation. The mean draft type of the ventilation planning is exhaust ventilation which can exhaust the dust and gas produced in the process of production effectually and provide an excellently working atmosphere for the work face .The productivity effect is increased by import the method of comprehensive mechanized coal mining which to satisfy the production target of 1.5million ton every year . The pitch of the coal seam is 2皛12?It seems the development mode of single level for slope mine is more reasonable. The wind press of the difficult time is 2873.81pa and the easy time is 1705.07pa .But in the mine aerator ,I select and put to use the fan whose model number is FBCDNo.32 which can offer the needed input air at the difficult time and easy time .It can provide the perfect safeguard for the mine ventilation and safety.
