History
Numa was laid out in 1871.

In 1907, fire destroyed the surface equipment of the Numa Block mine, then the most productive mine in the county. The Numa Block shaft was 150 ft deep, giving access to a 30 in coal seam. The Numa Block Coal Company also owned mines in Seymour, (about 8 mi to the west). In 1912, Local 875 of the United Mine Workers, based in Numa, had 392 members.

The original Numa Block mine was closed in 1915, after having undermined 240 acre. In 1911, the Numa Block Coal Company started a new mine, about a mile east of Numa. When fully developed, this mine employed 155 men, hoisting 300 tons of coal daily to ship 175 carloads of coal monthly. A new company town, Martinstown, was platted around this mine in 1913. The approximately 40 houses in Martinstown were frequently known as Shantytown. The mine closed in 1937, after undermining 96 acre. Aside from the blackened remains of the Martinstown slag pile, little remains of this mine today. In 1914, the Numa Block Coal Company produced over 100,000 tons of coal, ranking among the top 24 coal producers in the state.
