machines and the coal miner's work | ehistory,coal mines operated without electricity. electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (electricity was first introduced into ohio's bituminous coal mines in 1889.) the introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery..wage chronology: bituminous coal mine operators and united,mining methods such as the continuous mining machine, which integrates cutting and loading into a continuous sequence, and surface mining, which has made mining an outdoor industry. as early as 1913, half of the soft coal produced was mined with coal-cutting machines, but not until the de velopment of the pit-car loader—a simple conveyor.
