在矿井通风设计中,由于影响因素复杂和计算上的困难,对复杂网路和风机选择往往给予简化,难以进行方案选择。在扩(改)建矿山通风设计和通风管理中,一般只考虑局部风量要求来调整风量和风机。因此,技术上可靠性较差,经济上也不尽合理。用电子计算机解算矿井通风网路并选择最佳风机,能大大加快设计速度,确保设计质量和有效地进行生产管理。本文从矿井通风的基本原理出发,略述了在电子计算机上进行网路解算的步骤和最
In mine ventilation design, due to the complicated and computational difficulties, complex network and fan selection tend to be simplified, and it is difficult to choose the solution. Expansion (change) to build mine ventilation design and ventilation management, generally only consider the local air volume requirements to adjust the air volume and fan. As a result, the technical reliability is poor and the economy is not reasonable. Calculating mine ventilation network with computer and selecting the best fan can greatly accelerate the design speed, ensure the design quality and effectively carry out the production management. This paper, starting from the basic principle of mine ventilation, outlines the steps and the most
