矿井通风网路(下称风网)的解算,对于矿井通风设计和管理都很重要.但由于过程复杂,许多应该计算的问题过去没有计算;或者尽可能加以简化,使之局限于某些风网的个别区段,以便于手算.目前电子计算机迅速推广,用这种计算工具解算风网及其他通风问题,已引起越来越多通风工作者的兴趣.许多矿井已拥有相当数量的PC-1500或PB-700等袖珍计算机,可以说已经到了在 Mine ventilation network (hereinafter referred to as the wind network) solution, for the mine ventilation design and management are important, but due to the complexity of the process, many problems should be calculated in the past did not calculate, or as much as possible to simplify, limited to certain The individual sections of the wind net are convenient for hand calculations.At present, the rapid popularization of electronic computers and the use of such calculation tools to solve the wind net and other ventilation problems have attracted the interest of more and more ventilation workers. Many mines already have a considerable amount of The Pocket PC such as the PC-1500 or the PB-700 can be said to have arrived
