引言煤矿通风不仅对安全是必不可少的,而且,作为解决目前开采转向深部时地热引起井下温度升高问题的一个措施,也起到一定作用,因此,通风管理必须更为合理。对通风管理来说,巷道形状,特别是断面积及其周长是计算风量和风阻所必需的基础数据。 Introduction Ventilation in coal mines is not only essential for safety, but it also plays a role as a measure to address the issue of underground temperature rise caused by geothermal heat when deep mining is diverted to the present. Ventilation management must therefore be more rational. For ventilation management, the shape of the roadway, in particular the cross-sectional area and its circumference, are the basic data necessary for the calculation of air volume and wind resistance.
