Coal Miners
Coal mining is a dangerous job requiring skill and judgment. In the hand-loading era, an underground miner's workplace, usually called a "room," was only as high as the coal seam. A room in the Pocahontas seam could be more than 10 feet high, while workplaces in the Kanawha and New River seams often were no taller than four feet.

Dry jigging was introduced in the coal industry during the 1920s by applying the concepts involved in wet jigging technology to the design of pneumatic cleaning machines . Since then, significant improvements have been implemented in its conception and operation.
history of jigging machines in coal mining
The history of Coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.
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 …

History of Mining Equipment & Practices
Based upon a recent investigation of truck vs. rail haulage in bituminous-coal mines, Toenges and Jones conclude that with equipment in its present stage of development and within the range of conditions studied, for a new mine a dual haulage system would effect a saving in transportation cost if the round-trip haul exceeds 2.7 miles.
