For a time the coal industry "dwarfed all others" in the township, according to historian John Boucher, writing in 1906. Mines which once operated in Unity Township included those named Carney, Humphries, Dorothy, Marguerite, Mutual, Puritan (in Baggaley), Whitney, Jamison No. 20 (in Pleasant Unity), Hostetter, Beatty and St. Vincent's Shaft. Many of them were constructed in the period 1880 to 1900. All have long since closed. Extensive land remediation has taken place and few traces of the mines remain, but their names survive in township neighborhoods and streets.
