United Coal Mine No. 2 opened in 1911 in Buckner under the ownership of the United Coal Mining Company (later the United Coal Corporation). The mine was sold to the Old Ben Coal Corporation in 1960, and renamed Old Ben Coal Mine No. 14. Eight men were killed in an explosion in 1915, and one man was killed in a gas explosion in 1931. The mine was idle in 1933. Its last production was 1960.
The opening of the mines attracted immigrant workers. A large number of miners arrived, many of them from Austria-Hungary, Poland, Czechsolvakia and many of Lemko and Rusyn origin.  Many early immigrants trace their roots to the village of Myscowa in Poland. 
The mining community built a Russian Orthodox Church in 1913, which burned down in 1918. A second church was constructed. This church, the Nativity of the Virgin Mary, still stands today. It was built to mimic the construction of St. Ioasaph's in Muddy.
Along with the still standing Holy Protection Church in Royalton, St Mary's Orthodox Church in Madison, this church in Buckner was among the first of several Orthodox churches built to serve immigrant mining communities in southern Illinois. Others included the towns of Benld, Grand Tower, and Dowell.
This village had a number of taverns and nightclubs and was known as one of the biggest entertainment areas of Franklin County from the 1950s to the early 1980s.
