在地质勘探巷道的掘进过程中，必须供给足够的新鲜空气，及时稀释和排除爆破瓦斯，解决内燃设备尾气对巷道的污染，抑制放射性物质的危害，消除由于作业而产生的矿岩粉尘对人体的不良影响，调节井巷的温度和湿度，造成良好的气候条件。为达上述目的，抽出式、压入式、混合式的机械式通风法依然是简单经济、十分有效、应用最广的手段之一。多年来，国内外都做了大量工作，试图采用新的方法，来改进乃至取代传统的机械式通风法。但新的通风方法有待于进一步完善，以便在施工现场得到应用推广。本文述及了勘探巷道通风方法的研究现状，并就其研究方向谈几点粗浅的看法。
In the process of tunneling of geological exploration, enough fresh air must be supplied to timely dilute and eliminate blasting gas to solve the pollution of the roadway caused by the exhaust gas of internal combustion equipment, to prevent the harm of radioactive material and to eliminate the ore dust caused by the operation to the human body Adverse effects, adjust the temperature and humidity of the shaft, resulting in good climatic conditions. In order to achieve the above objectives, the withdrawable, press-in, and hybrid mechanical ventilation methods are still one of the simplest, most effective and most widely used means. Over the years, a great deal of work has been done at home and abroad in an attempt to adopt new methods to improve or even replace the traditional mechanical ventilation method. However, the new ventilation method needs to be further improved so as to be applied and popularized at the construction site. This article describes the status quo of research on the ventilation of exploration roadway and gives some superficial opinions on its research direction.
