Monitoring System For Coal Mine Safety Based On Wireless Sensor Network

Mining activities release harmful and toxic gases in turn exposing the associated workers into the danger of survival. This puts a lot of pressure on the mining industry. To increase the productivity and reduce the cost of mining along with consideration of the safety of workers, an innovative approach is required. Miner’s health is in danger mainly because of the toxic gases which are very often released in underground mines.

    These gases cannot be detected easily by human senses. In view of the problems of explosive, corrosion and accidents in underground coal mine production, this project designs a monitoring system based on Gas sensors and DHT sensor, Fire sensor and wireless sensor network LoRa, which can monitor the gas concentration, temperature and humidity parameters, and alarm when the parameters exceed the fixed value and simultaneously displayed on LCD. Experiments show that the system is stable in performance, accurate in measurement, and helpful to improve mine safety and reduce accidents.
