As 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.
