1.前言由于矿井开采深度的增加,所以矿井通风的规模亦逐渐趋向于大型化。因此,对通风设计提出了合理化和精确化的要求。当进行通风网路的计算时,应事先绘成各条巷道的通风阻力、矿井漏风量及扇风机特性曲线等基础资料,为此,就必须进行相当庞大的予备计算,这种计算如用 1. Introduction As the depth of mine exploitation increases, the size of mine ventilation also tends to become larger. Therefore, the ventilation design put forward the requirements of rationalization and precision. When calculating the ventilation network, the basic data such as the ventilation resistance of each roadway, the amount of air leakage in the mine shaft, and the characteristic curve of the fan fan should be drawn in advance. For this reason, a rather large preliminary calculation must be carried out,
