摘要
利用分析数学的压缩映射原理,对矿井通风网络非稳定流动数学模型进行了分析,得出了数学模型数值解收敛的条件,确定了以惯性系数排序选择最小生成树的回路选择方案,为矿井通风网络非稳定流动数学模型数值解的收敛性提供了理论依据.
Based on contraction mapping theorem of analysis mathematics, the non-steady flow mathematical model of mine ventilation network was analyzed. The convergent condition of numerical solution to the mathematical model was obtained, and the selection scheme of circuit according to inertial coefficient searching the least spanning tree was put forward. Theoretical basis on the numerical solution convergence of the non-steady flow mathematical model is provided.
