以往矿井通风网路的解算方法,都是把分支风路的风阻作为已知量,风量作为未知量求解的,本文用求解非线性方程组的Newton-Raphson方法及其变种,在已知网路中部分风路风阻和其它部分风路风量时解算矿井通风网路,求出各个风路的风量或风阻。这种算法已经编制了DJS-21机ALGOL_(60)算法语言程序,通过实际计算,效果尚好,计算效率较高,为通风设计确定网路结构和风阻分配给出了直接求解的方法。
In the past, the method of solving the mine ventilation network was to use the wind resistance of the branch airway as a known quantity and the air volume as the unknown quantity. In this paper, the Newton-Raphson method and its variants for solving nonlinear equations are used. Road part of the air resistance and other parts of the air flow path when the mine ventilation network to solve, find out the amount of air flow or wind resistance. This algorithm has been compiled DJS-21 ALGOL_ (60) algorithm language program, through the actual calculation, the effect is good, the calculation efficiency is high, for the ventilation design to determine the network structure and wind resistance distribution is given a direct solution.
