<span style="font-family: 'Times New Roman',serif; font-size: 10pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: DE; mso-ansi-language: EN-US; mso-bidi-language: AR-SA;">Targeted at the potential fire in coal mine production, this paper proposes a coal mine fire monitoring system based on Zig-bee technology, and discusses the network data transmission process in the system. When the system is applied to an actual coal mine, it achieves a sound fire monitoring effect. The wireless sensor network (WSN) coal mine fire monitoring system consists of such three subsystems as data acquisition subsystem, control center subsystem and emergency response subsystem. With sensor nodes as the basic unit, the WSN is divided into five parts: sensor module, treatment module, wireless communication module, location module and power supply module. The system can monitor the air temperature, humidity and smoke concentration of fire in the coal mine, and provide effective basis for monitoring department to make decisions on fire prevention and control measures. The on-site monitoring test shows that, in the event of a fire, the WSN can monitor the trend of fire in the coal mine effectively, reflect the temperature distribution in details, and issue alarms accurately. The conclusion offers a theoretical reference for the development of coal mine fire monitoring technology.</span>

Summary
Underground coal mine production conditions are very poor. What is worse, there are a variety of hazard sources, such as gas, groundwater leakage, initial roof pressure and fire. The fire caused by spontaneous combustion of coal and gas explosion has become a global disaster, which poses a serious threat to the work safety of the coal mine and the safety of the natural environment, and results in tremendous economic losses [1,2,3,4]. Recent years has seen the rapid development of a new wireless network technology, the wireless sensor network (WSN). It realizes the seamless connection between people and the monitoring area through sensor nodes scattered in the monitoring area and real-time monitoring of environmental regions [14]. The conclusion offers a theoretical reference for the development of coal mine fire monitoring technology
