Paper Title
Coal Mines Monitoring And Security System

Based on continuous revolution of coal mining technology,this paper puts forward a project about safety monitoring system of coal mine using Zigbee technology and RS485 interface. A system is designed using group of sensors which monitors the different environmental condition in underground mines and if value exceeds from threshold value, then the Miners are informed through Alarm. Another module is wireless sensor network software, which is developed to trace and locate underground miners by sending the alert message to control stations. The paper shows that the system is flexible in the architecture of software and hardware, and can easily extended to other mine safety production fields.
