Aggregate mining in New York takes two forms. The simplest process involves sand and gravel excavation. Sand and gravel are unconsolidated minerals that can be mined using a front-end loader or excavator then processed through crushers and screens to make the desired end product. Mining crushed stone is more involved because the deposits are ...

Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.
