The introduction of lighting systems into underground coal mines in the United States has been a controversial issue. Longwall lighting, however, has received widespread management and miner acceptance with tangible benefits being realized in both safety and production. Based on the experience that longwall operators have had with their lighting systems, the following general conclusions seem appropriate: (1) a wide selection of lighting equipment and suppliers exists. (2) Intrinsically safe fluorescent systems are more widely used. (3) The majority of operators reported that maintenance requirements are low or moderate with only a few experiencing major maintenance problems. (4) The biggest maintenance problem has been damage to the system power cables. This paper describes the present state of the art and status of longwall lighting in the United States. Specific subtopics discussed are as follows: review of MSHA lighting regulations and requirements for longwalls, overview of available lighting hardware, installation procedures and costs, and analysis of installations to date.
