【摘要】 在矿井通风仿真系统的基础上,运用网络分流的理论,在已知基本关联矩阵和基本回路矩阵、初始风量和多主扇的性能参数下,当网络中某条分支的风量有变化时,求出其它分支风量的变化量和另外一个主扇变化后的性能参数,可有效提高选择主扇性能参数的精确度。更多还原

【Abstract】 Abstract: On the basis of the mine ventilation simulation system,using network branch theory,on the conditions that basic incidence matrix and basic circuit matrix,initial wind amount and the performance parameters of multiple main fans were given,when the wind amount of one branch changes in the network,the wind amount of other branches and the performance parameters of another main fan after change were found out.It effectively improved the accuracy of selecting the performance parameters of main fans.更多还原
