针对矿井环境复杂、布线困难的特点，根据矿井实际环境和系统需求，构建了井下无线传感器网络的四层分簇式链状拓扑结构。研究了固定节点网络、移动节点网络、整个网络的拓扑形成过程，其中移动网络拓扑结构的构建采用组合加权的LEACH算法来实现，实验仿真表明该算法能够有效降低移动节点的能耗，延长整个网络的生命周期。同时，针对井下人员的移动性，分别提出了移动节点的加入策略和离开策略。该系统具有多层次、稳定性好、可扩展性强等特点，为矿井监测系统进一步的数据传输、融合和人员定位奠定了较好的基础。

Aiming at the characteristics of complex environment and wiring difficult in mine, according to mine real environ-ment and system requirements, a four-storey clustering type chain topology of wireless sensor networks in the mine is built. The topology formation processes of stationary node networks, mobile node networks and whole networks are researched. Specially, the topology of mobile node networks is built by combination weighted LEACH algorithm ,and the experiment simulation shows that the algorithm can reduce energy consumption effectively, and prolong the lifecycle of whole network. Meanwhile, aiming at the mobility of mine worker, the join strategy and leave strategy of mobile node are put forward respectively. The sys-tem has the specialties of multi-level, good stability and strong extensibility, which provides a good foundation for further data transmission and fusion and personnel location of mine monitoring system.
