Hydraulic fill is one of the most popular backfill materials used to fill these underground voids, and is generally placed in the form of a slurry at water contents in the range of 30-45%. Porous brick barricades are placed across horizontal access drives to retain the hydraulic fill, allowing free drainage and enabling the hydraulicHydraulics in Mining - Aggressive Hydraulics,This is different from underground mining, where the overburden is left in place. Forms of surface mining that are prevalent in the United States are strip mining, mountaintop-removal mining, and open-pit mining. Surface mining is a two-part process, and both processes involve the power of hydraulics. Powerful earthmovers remove the overburden, allowing access to the minerals. Then gigantic excavators extract the minerals from the earth. Even transporting the materials from the mining
