Abstract:

Underground coal mining is a particularly dangerous profession and works in a particularly harsh environment, with frequent fire and explosion incidents and thousands of deaths. In the world as well as in Vietnam, when gas fire and explosion incidents occur, they are huge disasters in terms of both people and equipment. In this study, the authors introduce IoT (Internet of things) technology for early warning of explosive gases and dust in underground coal mining. This technology includes sensors that measure data on gas, dust, temperature, mine humidity and transmits data to the server center. On that basis, monitoring the measured values transmitted from the sensor will early detect risks and unfortunate incidents in underground coal mining.
