根据煤矿通风网络的一般特点,提出以通风网络气体流动的基本方程为数学理论基础,并划分出无节点单元、单节点单元、三节点单元和四节点单元,并介绍各自特点,用划分的单元对鸡西矿业集团正阳矿某通风网络进行了有效的组合,为煤矿现场通风系统节能工程的实现提供理论基础。 According to the general characteristics of coal mine ventilation network, the basic equations of gas flow in ventilation network are put forward as mathematical theory basis, and the nodeless cell, single node cell, three-node cell and four-node cell are divided and their characteristics are introduced. The effective combination of a ventilation network in Zhengyang Mine of Jixi Mining Group provides a theoretical basis for the realization of energy-saving project of ventilation system in coal mine site.
