Safety Monitoring System for Coal Mine Workers using Different Sensors

In this paper design and developed Safety measures for mine workers which are most essential in underground mining areas/sections. Here we are presenting MEMS based sensors network used to monitor the environment parameters of underground mine area and sends all sensed parameters/data to ARM processor. ARM processor is used to build a fully automated measuring system with reliability, high accuracy and smooth control. Upon detecting critical conditions/issues alert system starts and the same information is transmitted/passed to remote location by initiating modules based on RF communication Methods. The observed changes in the parameters will also be displayed in pc which makes easier for the underground control center to monitor and to take necessary immediate action to avoid damages and alerts through a mobile message. An electrochemical gas sensor array system is proposed for health and safety monitoring. The system incorporates a custom mine temperature ionic-liquid gas sensor array, a custom multi-mode electrochemical sensor readout board, and a commercial low power microcontroller board. Electrochemical sensor array was utilized to significantly decrease power, cost and size. In underground coalmine major of accidents occurred are based on fire and natural gas and overheating of surroundings. We are also considering the health condition of a person using Fall-Detector, made of MEMS-Accelerometer.
