Slope mining is a method of accessing valuable geological material, such as coal. A sloping access shaft travels downwards towards the coal seam. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively.
In mining, slope refers to the angle of inclination of a surface or underground excavation. It is an important factor in determining safe and efficient mining operations, as steeper slopes can affect stability and the cost of extraction. Geotechnical engineers often assess and design slopes to ensure the safety of miners and the integrity of the mine workings.
Forms of subsurface mining include drift mining, slope mining, shaft mining, and room and pillar mining. These methods involve accessing minerals or resources beneath the Earth's surface through tunnels, shafts, or other underground workings.
i don't know the types of subsurface mining, but i know some facts.surface mining is safer and easier than subsurface mining.You don't have much air underground.It has no or very little advantages compared to surface mining.
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining
Here are two of the main categories of mining:Underground Mining - Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined. Shaft mines are the deepest mines; a vertical shaft with an elevator is made from the surface down to the coal.Surface Mining - Surface-mining methods include area, contour, mountaintop removal, and auger mining. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. Huge dragline shovels commonly remove rocks overlying the coal (called overburden).
No, if the minerals are deep, slope mining is not possible.
