均压通风防火是一项新技术,全国各地都在试验,而以淮南使用最早,并在实际应用中取得了一定的成绩。十多年来各地对消灭井下采空区自然火灾都作了大量工作,取得了许多宝贵的经验。在这方面,国外已导出“势能公式”。淮南也得出一些计算方法。对于在理论上如何确实地找到一个理想的计算公式来指导这一工作,将是今后一个努力的方向。现在就以我个人的工作体会,提出以下认识: Pressure equalization ventilation is a new fire prevention technology, all over the country are in the test, but the earliest use of Huainan, and in practical applications has made some achievements. Over the past decade or so, a great deal of work has been done on eliminating natural fires in the underground goaf and many valuable experiences have been gained. In this regard, the “potential energy formula” has been exported abroad. Huainan also come to some calculations. How to find an ideal formula in theory to guide this work will be a direction of efforts in the future. Now with my own personal experience, put forward the following understanding:
