This is an old favorite post of mine I thought I might recirculate. The subject matter shaping rocks is about as old as prehistory and we know that is some really, really, really old stuff. In fact, it is an excellent concept for placing the interaction between Mankind and Rocks closer to Infinity.

The benches are mined away as work descends to the bottom of the deposit or to the haulage way, so that spectacular steep side walls may result if the walls do not slough in. Mining can be quite selective, and little waste rock is thrown on the surface dumps. The principal environmental objection to the method is difficulty in reclamation of the surface of the mine area. 2 February 2016 Prof
Best practices: Drilling and blasting. When these two are managed separately, you are likely to get non-uniform rock fragmentation. If you combine the processes, For consistency in results, it should really be the other way so that a straighter quarry face results after each blast.
than one face so that simple blasting patterns can be used to remove the rock. In the illustration that follows (Figure 8-4) shows a typical bench cut with two free faces and fired with one delay per row. Figure 8-5 indicates that the direction of throw of the blasted rock can be
Establishing a self-sustaining cover of vegetation is the best way to stabilise disturbed sites in the long term. Revegetation also minimises the visual impact of quarries. Generally, the vegetation type which existed before the disturbance, or a similar vegetation type will regenerate most successfully.
In addition, establishing roads or tunnels for vehicle access is critical to the profitability and efficiency of the mine. A quarry manager needs to oversee each cut made from the quarry; marble mined along the "vein" of the deposit will have a very different look than marble that is "cross-cut" across the vein.
The simplest horizontal mine is the least effective: mining forward in a straight line. Horizontal mining should really be called “branch” or “feather” mining, because the best way to use it is to dig a horizontal shaft and then create branches off the sides of the main tunnel.
