Contact usA breaker boy was a coal-mining worker in the United States and United Kingdom [citation needed] whose job was to separate impurities from coal by hand in a coal breaker.Although breaker boys were primarily children, elderly coal miners who could no longer work in the mines because of age, disease, or accident were also sometimes employed as breaker boys.
Contact usThese tunnels result from the excavation of a series of "rooms" into the coalbed, leaving "pillars" or columns of coal to help support the mine roof. In conventional room-and-pillar mining, the coal is broken up by explosives, loaded onto a vehicle by a mechanized loading machine, and transported from the production area by shuttle cars.
Contact usAs a result, coal mining needed larger amounts of capital as new systems of pumping, ventilation, and extraction required the implementation of steam power in mines. By the 1890s, electric cutting machines replaced the blasting method of loosening the coal in some mines, and by 1900 a quarter of American coal was mined using these methods.
