中文摘要：

为研究矿井通风网络的社团结构特征和有效控制灾害在通风网络中的传播范围,根据通风网络的连接特点对传统的GN算法进行改进,以淮南某矿井的通风网络结构为例进行说明,发现矿井通风网络具有较强的社团结构特征;引入强弱社团结构和外内连接边数比后,社团结构的划分更符合实际。根据矿井通风网络社团间的连接关系,就会找到灾害传播的关键分支与节点并加以控制,降低灾害对相邻社团危害程度,控制灾害的蔓延范围。

英文摘要：

The traditional GN algorithm was improved in the light of the link characteristics of mine ventilation networks in order that the characteristic of community structure can be researched and the disaster spreading sphere can be controlled.The strong characteristic of community structure was found with the improved GN algorithm and the example of a certain mine in Huainan.The number of community can be given exactly when the strong and weak community structures and the proportion of outer to inner relating lines were introduced.Based on the relation of community structures,the key lines and nodes would be identified and controlled,which can decrease the damage degree to the next community and control the disaster spreading sphere.
