The Blue Diamond Coal Company operated the coal mine at Royal Blue for years. During that time miners and their families were housed in small single-family homes with running water and outdoor toilets. The only commercial service available to the miners was a company store where the workers could use scrip to make purchases. Few owned cars and the only other way to travel was by a bus which transported miners from other areas in the morning and returned them in the evening.
For years school for students in grades primary through 5th grade was held in a 3-room house. c1947 a cinder block school which included indoor bathrooms was built for students through 8th grade.
Baptist and Holiness congregations shared the 3-room school for their services.
