Kay Moor coal mine exhibits important examples of early 20th century mining technology. Its two extant inclines and headhouse are examples of specialized adaptations to mining coal from outcrops located on steep slopes. The processing plant contains a Simon-Carves Baum Jig coal washer, shaker screens and other equipment introduced during the 1920's, an important era in the transition to mechanically cleaned coal. Over the years the original two-word spelling of Kay Moor has been modified to one word so that most current maps and literature spell the mine's name as Kaymoor.
