For more than one hundred years, until the 1920s, coal production involved blasting a seam of coal and loading it by had into a mine car. In the late 1920s, operators introduced machines into the mines, including the coal loader. In this book, Keith Dix explores the impact of technology on miners and operators during a crucial period in industrial history. Dix reconstructs the social, political, technical and economic environment of the "hand-loading" era and then views the evolution of mechanical coal technology, including the inventions of Joseph Joy. He also examines the rise of the United Mine Workers under John L. Lewis, and the expanded role of the state under New Deal legislation and regulations.
