Causes of water spray nozzle clogging on coal mine face machines were investigated and determined. This led to the design, development, and subsequent successful field testing and demonstration of a non-clogging water spray system. The non- clogging system was installed on three different continuous-mining machines. Followup tests showed that nozzle clogging was reduced by more than 90 percent. Also, on one section respirable dust concentrations were measured before and after the two periods, there was significantly more coal mined after the system was in operation.
