For reserve calculation, the mineral deposit is transformed into an analogous geometric body made up of one, several, or an aggregate of close-order solids that best describe the size, shape, and distribution of the variables. This conversion reduces and distorts the original mineral deposit.
Maptek's Vulcan software is helping one savvy Greek quarries manager accurately plan and manage his marble reserves. Guy Woodford reports. The English idiom 'It's all Greek to me' refers to something that is difficult to understand. How best to secure accurate mineral reserves data and find the right platform to clearly interpret it can fit such a turn of phrase, but one Greek ...
This document is intended as a guide specifically for quarry operations; however, quarry operators can seek variances, exceptions, or revisions based on site-specific facts. Quarries in the Edwards Aquifer include operations that produce dimension stone, aggregate, and sand and gravel. These quarries also come in a wide range of sizes.
Because of the investment required for modern aggregate operations (time and capital), companies typically require a minimum of 15 to 25 years of reserves to open a quarry. In …

Dispositions of Crown quarry land are made by public tender or direct offer in response to individual application. Public tender is the preferred method of disposition for new deposits where materials are in high demand. Public tender is also used for already-known deposits where a quarry tenure or reserve is not being replaced.
This method is slightly advance version of polygonal method. In this method holes are connected to adjacent holes. This divides the ore body into a series of triangles (T 1, T 2, – – – – – -, T n).Each triangle rests on the plane of the map and represents a base area of an imaginary prism with edges t 1, t 2, t 3 equal to vertical thicknesses of intercepted mineralisation.
