矿井通风方式有三种:压入式、抽出式和压抽混合式。这三种通风方式的差别主要是在整个通风路线上形成了不同形式的压力分布状态,从而在入排风量、漏风量、风质和受自然风流干扰的程度等方面出现了不同的通风效果。判定通风方式的好坏,要从矿山的具体条件出发,看哪一种通风方式有效风量高、排烟速度快、风质好,并易于管理。东北地区的矿山还要考虑是否有利于冬季入风井防冻。下面对三种通风方式分别进行分析。
Mine ventilation in three ways: press-in, draw-out and pressure pumping hybrid. The difference between the three ventilation modes is that different forms of pressure distribution are formed in the entire ventilation route, so that different ventilation effects occur in terms of air intake and exhaust volume, air leakage volume, wind quality and degree of interference with natural wind flow . Determine the ventilation mode is good or bad, starting from the specific conditions of the mine to see which of the ventilation mode effective air volume, exhaust fast, good windy, and easy to manage. Northeast mine also consider whether it is conducive to the winter air intake antifreeze. The following three kinds of ventilation were analyzed.
