K D = around 3 for natural quarry rock; K D = around 10 for artificial interlocking concrete blocks; S r = (ρ r / ρ w is the relative density of rock, i.e. (ρ r / ρ w - 1) = around 1.58 for granite in sea water; ρ r and ρ w are the densities of rock and (sea)water (-) θ is the angle of revetment with the horizontal
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
A geologist's hammer, rock hammer, rock pick, geological pick, or informally geo pick is a hammer used for splitting and breaking rocks. In field geology, they are used to obtain a fresh surface of a rock to determine its composition, bedding orientation, nature, mineralogy , history, and field estimate of rock strength.
The Van der Meer formula is a formula for calculating the required stone weight for armourstone under the influence of (wind) waves.This is necessary for the design of breakwaters and shoreline protection.
Normative mineralogy is an estimate of the mineralogy of the rock. It usually differs from the visually observable mineralogy, at least as much as the types of mineral species, especially amongst the ferromagnesian minerals and feldspars, where it is possible to have many solid solution series of minerals, or minerals with similar Fe and Mg ratios substituting, especially with water (e.g ...
For comparison, on the whole Idaho 55 project, ITD initially expected to take 140,000 cubic yards of rock from the hillsides, or what equates to more than 11,000 truckloads.

A rock mass with a high RMR before the adjustment factors are applied has a high reinforcement potential, and can be reinforced by, for example, rock bolts, whatever the MRMR value might be after excavation. Contrariwise, rock bolts are not a suitable reinforcement for a rock mass with a low RMR (i.e. has a low reinforcement potential).
