    In 1974 the mine cars and hoisting equipment were gone, sold for scrap. All that remains today is the partially demolished wash house, the concrete floor of the hoist house, a few scattered mine car remains, and the partially filled air shaft that led to the Clark vein.

  • Mining Methods - Kansas Geological Survey

    Drift or slope mining methods can be used as long as the coal face is relatively close to the mouth of the mine. When the coal face has receded a distance greater than 500 or 600 feet, the time and labor consumed in getting coal from the coal face to the surface is so great that the mine must be abandoned. ... Shaft mining has been used more ...

    Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

Empty coal cars were typically pushed into the mine by hand. After they were loaded, a team of mules was brought in to pull them out.Some of the .

  • Slope mining - WikiMili, The Free Encyclopedia

    Slope mining is a method of accessing valuable geological material, such as coal or ore. A sloping access shaft travels downwards towards desired material. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively. In slope mining, the primary access to the mine is on an incline.

    Apr 25, 2017 · Shaft mining is employed to reach the deepest ores. There are shafts or tunnels for miners and heavy equipment to move in and out. A different shaft is used for transportation of extracted ore and an air shaft for ventilation. Slope mining is done with slanted shafts that are not too deep and helps to extract ore that occurs parallel to the ground.

    Iron, copper, stone, and gravel are usually extracted by open-pit surface mining, in which a giant hole is dug. In strip mining, a trench is dug to extract the minerals. Subsurface mining, which is underground, may be done with a shaft mine or a slope mine. A shaft mine is a direct vertical shaft to the vein of ore.
