Coal is a major element for development, an important energy source for power generation, and it is an essential part of the manufacturing of alumina, iron, steel, cement, and other resource products necessary for modern living. The extraction of coal from the field is known as coal mining. Safety and security are critical components in the mining sector. Even they take certain precautions to avoid accidents in the underground mines. Still, accidents continue to occur in underground mines, resulting in a greater number of disasters. Temperature, gas, fire, and water are the key elements involved in many accidents. This project monitors these parameters using Arduino UNO and provides safety and alert for coal mine workers to minimize the accidents. To improve underground mine safety, a reliable communication system must be built between underground mine workers and a fixed ground system. The communication network must not be interrupted at any time or under any circumstances. A buzzer is used for alerting the mine workers. Using IoT and Buzzers, this system alerts the admin as well as the workers when any abnormalities are found inside the coal mine.
