IoT Based Coal Mine Tracking and Worker Safety Emergency Alert

Abstract

Abstract: Due to global warming and climate change, there are now difficult conditions in the coal mining industry. Automation in the field of coal mine-shaft is in fact necessary to reduce costs and boost profitability while also improving product quality, and it will also reduce diggers' efforts. Mining is both necessary for the manufacture of goods, infrastructure, and services that improve people's lives and one of the world's most dangerous trades. The need for coal as a source of energy is always high and significant. However, hundreds of people have died in mining accidents around the world, and working in the earth poses a variety of security and health risks. Underground miners in some nations lack safety and social protection, and in the event of injury, they may be left to fend for themselves. There are also negative societal consequences, such as displacement and lost income. Among all industries, the mining industry has the greatest rate of occupational mortality. Rock falls, a sagging roof, and a sagging pillar are all common causes of workplace deaths. Underground mines provide a lot of case studies. To deal with all of these tragedies, we need to improve communication technology, which will be used to create an intelligent sensing and warning system. For communication within the mines, RF technology has been adopted. So, utilizing a microcontroller-based circuit on worker safety, we suggest a mining tracking and safety system for the mining business. To detect workers moving throughout the mining site, we deploy RF-based circuitry. The main microcontroller was an ARDUINO UNO. The system employs ATMEGA microcontroller-based RF tracker circuitry to transmit and receive data through the usage of an EM-18 RFID reader module and RFID cards. This aids in the tracking of workers' present locations across the entire mining site. The DHT11 sensor is used to determine the current temperature and humidity. The accelerometer sensor is used to determine whether or not a worker has fallen. MQ2 and MQ135 sensors are used in mines to detect dangerous chemicals and smoke and inform workers. A flame sensor detects a fire in a mine and alerts the workers. Furthermore, safety is the most important aspect of every industry. Safety and security are extremely important in the mining business. Each RFID card circuit includes an emergency button to prevent any form of mishap. When this button is touched, an emergency alert appears. This technology can be used to safeguard the safety of mine workers through the usage of IoT
