Monitoring and Surveillance System Using PLC for Mining Industry

The research study concerns people's life and property safety to inform coal mine authorities about releasing poisonous gases inside the mine It may have a significant role in coal excavation safe production and the life of coal mine workers. The system integrates multi parameters detection using a PLC controller to collect underground various environmental data (methane gas, CO2, and temperature). To get rid of poisonous gases inside a coal mine, firstly, the gases will be detected through gas sensors, and poisonous gases will be exhausted through a proposed exhaust system. To maintain the level of oxygen inside the mine, a fresh air supply will also be designed. Furthermore, the water sprinkler system will also be installed to neutralize the hazardous gases. When the number of specific gases exceeds the limits, an alarm will be generated, and authorities will receive an SMS through the GSM module. A prototype is deployed with different gas sensors, water sprinklers, controllers, and an exhaust and fresh air induction system. This project will result in the safety of the worker's life and more production of coal inside coal mines.
