Slope geometry design as a means for controlling rockfalls ...

In mining, the main aim was to ensure the stability of the general slope—an aim that was compatible with financial exploitation of the mineral. Ensuring bench stability usually implies very low dipping slopes, which generally renders mining non-profitable, and so general slope stability, rather than bench stability, is

and slope failures. The best control for protecting people working near faces is a quarry/ mine plan or design that has considered your site’s particular geological and geotechnical characteristics. Planning for excavations requires a good understanding of ground conditions and identification of ways to avoid potential ground failure.

Slope mining - Wikipedia

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.

In open-pit mining, the slope angle of a single step is generally set between 60 and 65° to prevent slope collapse. Therefore, it can be seen that when the crack dip angle in the rock is gradually parallel to the step slope, the decomposition force perpendicular to the crack is gradually reduced, which easily tends to cracking and expansion of ...
