2. Mineral resource estimation - Wikipedia

   en.wikipedia.org/wiki/Mineral_resource_estimation

   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.

3. Earthworks (engineering) - Wikipedia

   en.wikipedia.org/wiki/Earthworks_(engineering)

   In that case, earthwork software is principally used to calculate cut and fill volumes which are then used for producing material and time estimates. Most products offer additional functionality such as the ability to takeoff terrain elevation from plans (using contour lines and spot heights ); produce shaded cut and fill maps; produce cross ...

4. Cut and fill - Wikipedia

   en.wikipedia.org/wiki/Cut_and_fill

   A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut & Fill Software showing cut areas highlighted in red and fill areas shaded in blue. In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...

5. Normative mineralogy - Wikipedia

   en.wikipedia.org/wiki/Normative_mineralogy

   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 ...

6. Rock mass rating - Wikipedia

   en.wikipedia.org/wiki/Rock_mass_rating

   A rock mass rating system provides a method of incorporating some of the complex mechanics of actual rocks into engineering design. Moreover, the system was the first to enable estimation of rock mass properties, such as the modulus of deformation, in addition to providing tunnel support guidelines and the stand-up time of underground excavations.

7. Infiltration (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Infiltration_(hydrology)

   Infiltration is a component of the general mass balance hydrologic budget. There are several ways to estimate the volume and water infiltration rate into the soil. The rigorous standard that fully couples groundwater to surface water through a non-homogeneous soil is the numerical solution of Richards' equation.
