Coal mining is the biggest trade in the world. Coal mining is the process of extracting minerals from the ground. In the coal mining occupational accident and hazardous events are occurs commonly. As a result of these accidents many skilled workers and laborers lost their life. There is no advent precaution measure to detect the hazardous event occurred in coal mining field and to provide an alert system. A classic model is to monitor the condition of mining fields is designed. The model consists of two sections namely nodal section and helmet section. The Helmet section consists of Infrared [IR] sensor and heartbeat sensor. If the helmet is removed accidentally that will be indicated by the Infrared [IR] sensor and heartbeat rate of the miner is detected using heartbeat sensor. Nodal section consists of Temperature, metal detector, gas and PIR sensors. These sensors will measure the environmental condition of the mining field. The sensed parameters are communicated via ZigBee. Arduino and ARM 7 controllers are placed in helmet and the nodal section respectively for the processing. The monitored parameters are uploaded to cloud for permanent storage using internet of Things [IoT].
