The first decades studied in this course were a time when Americans lived without using electricity. 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 Ohios bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. Continuous miners are used primarily in room-and-pillar mines and operate similarly to longwall machines. They account for nearly 45 percent of all underground coal mined. In 1935, two percent of West Virginias coal was loaded by machines 20 years later, 99 percent was machine loaded.
