    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.
