随着生产建设的发展,很多矿井已向深部开拓,新水平的通风设计与瓦斯涌出量的预计值关系很大,它不但直接关系到风机选型和通风方式的确定,而且涉及到工程投资、生产成本,甚至矿井生产能力。因此,正确预计新水平的瓦斯涌出量是有现实意义的。本文就我局矿井新水平延深设计中遇到的实际问题,对瓦斯涌出量的预计方法,谈点肤浅认识。
With the development of production and construction, many mines have been opened up to the deep. The new level of ventilation design has a great relationship with the expected value of gas emission. It not only has a direct bearing on the selection of fan types and ventilation modes, but also involves the investment in engineering , Production costs, and even mine productivity. Therefore, it is of practical significance to properly predict the new level of gas emission. This paper discusses the practical problems encountered in the design of the new depth of mine in our bureau and gives some superficial understanding of the expected method of gas emission.
