Modern smart mining increasingly depends on the use of sophisticated electrical and electronic systems for improved safety and better productivity. With more electronic systems being introduced underground, the mining industry is facing electromagnetic compatibility (EMC) issues caused by electromagnetic energy emitted by one device adversely impacting the normal function of another. This presentation provides an overview of electromagnetic interference (EMI) research for underground coal mines, with the goal to help the mining industry to better understand the challenges posed by EMI and to promote EMC in underground coal mines. We will first start with an introduction of EMI, followed by an overview of NIOSH research on EMI in mining. Some representative EMI incidences occurred in the mining industry will be given. Mitigation strategies that can be potentially used to cope with EMI issues and some best practices to overcome EMI will be discussed.
