复杂的矿井通风系统不仅对风网解算提出了更高的要求,对构建的通风网络进行风网检查也变得极其重要。首次提出了风网有效性分析的概念,通过分析改进的回路风量法解算的要求,从数据检查、风网检查和收敛性分析三个方面对通风网络图有效性进行了系统深入的分析,实现了相应的风网检查算法。通过进行强连通性分析可以使假拓扑风网更接近真实风网,通过对固定风量检查可以找出拓扑关联重复性设置的固定风量分支;通过对回路进行独立性检查和收敛性分析使得构建的通风网络尽量满足风网解算的要求,避免回路假收敛并提高解算收敛速度。

The mine ventilation systems being more and more complex have come up with higher request to the ven-tilation network calculation, and the inspection on constructed ventilation network becomes extremely important. The concept of ventilation network effectiveness analysis was put forward at first.By the analysis on calculating re-quirements of the improved circuit air-quantity method, the ventilation network effectiveness was analyzed systemat-ically and thoroughly from the data inspection, the ventilation network inspection and convergence analysis.The al-gorithm of ventilation network inspection was achieved.By analyzing the strongly connected digraph, the false to-pology ventilation network could be closer to the true ventilation network.Based on the fixed air-quantity inspec-tion, the fixed air-quantity branches with repetitive setting topology correlation could be found out.By the inde-pendence inspection and convergence analysis on the circuit, the constructed ventilation network could better meet the requirements of ventilation network calculation, which can avoid false circuit convergence and improve the speed of convergence.
