提出了自然风压在矿井中的三种表现形式，论述了自然风压的实质是井上下热力因素等在矿井一切井巷中所产生的水平热压差，矿井的自然热位差是水平热压差叠加的结果。把自然热位差当做自然风压在理论上是模糊的，是不符合矿井实际情况的。
The paper presents three manifestations of natural wind pressure in mines. It discusses that the essence of natural wind pressure is the horizontal differential pressure caused by all the factors such as thermal factors in and around the mine. The natural thermal potential difference of mines is horizontal heat The result of superposition of pressure. Taking the natural heat potential as the natural wind pressure is theoretically ambiguous and does not conform to the actual situation of the mine.
