Based on the topographic features of coal mine and its gas distribution,a design of mine monitoring network nodes based on ZigBee technology which was applied in coalmine safe system was proposed.In this design, ZigBee-based wireless sensor network,which consisted of sensor nodes,router nodes and one coordinator. Based on ZigBee technology analysis of wireless sensor network architecture, the core of sensor network node is CC2430,this node could complete several kinds of safe information gathering and transporting in coa1,and the design of system structure,hardware and software was discussed in detail.%本文根据煤矿地形特点和矿井分布情况，提出了一种基于ZigBee的无线传感器网络在煤矿安全系统中的应用方案。无线传感器网络由传感器节点、路由节点和网络协调器组成，根据其工作原理和节点体系，设计了以CC2430为核心的传感器网络节点，该节点装置能够完成负责煤矿安全指标信息的采集和传输，并给出了这种传感器节点的硬件设计和软件流程。
