通过对回路风量法解算矿井风网的原理及数学模型的分析,提出了独立回路间相互交换的方法。经数学推导,证明了牛顿法和拟线性法解算矿井风网的收敛速度与回路的圈划间没有任何直接的关系,因此认为采用这两种方法解算矿井风网时,用传统的“最小生成树” 法圈划回路是一种繁琐的不可取的方法。最后提出了圈划回路的简便方法,该方法简化了风网解算程序,而且有助于缩短计算机的运行时间。 Through the analysis of the principle and mathematical model of the mine wind network by loop air volume method, a method of mutual exchange between independent circuits is proposed. The mathematical derivation proves that Newton method and quasi-linear method have no direct relationship with the loop delineation of the mine wind network. Therefore, when using these two methods to solve mine wind network, the traditional “ Minimal Spanning Tree ”method of circle tracing is a cumbersome and undesirable method. Finally, a simple and convenient method of looping circuit is proposed, which simplifies the wind network solution procedure and helps to shorten the running time of the computer.
