Quarry drill and blast: a vital first operation
The software includes a calculation that takes into account the additional energy required at the toe of the blast. In various studies this procedure has been shown to result in a much better energy balanced blast. In this case the variation of explosive energy is achieved by changing the type of explosive employed in the hole.

known as OEE to crushing plant in aggregate quarries. Operation metrics of data collected through crushing plant report system (CPRS) of F and P quarry, Abuja, Nigeria, have been adopted for the OEE calculation of the crushing plant. with the numerical working of the metrics, this paper explains the step by step method for the evaluation
Ore Reserve Estimation Methods
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.
Reserve Estimation Through Conventional Method and …
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.

Crown Land Quarry
Authorization Requirement Description; Aggregates & Quarry Materials Tenure (Land Act) 1. Age 2. Citizenship: 1. 19 years of age minimum 2. Canadian Citizen or corporation, Permanent Resident or authorized to work in Canada
Land use
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.

Valuation of Aggregate Operations for Banking Purposes
Aggregate is typically divided into two components:! Fine aggregate including sand – material passing a 3/8-inch screen sieve, essentially all passing a # 4 sieve (i.e., a 0.187-inch square opening). ! Coarse aggregate including gravel – generally considered being crushed stone or gravel, almost all of which is retained on a No. 4 sieve.
Ore Reserve Estimation Methods – Detailed Tutorial
Mineral Resources are defined as the concertation of material of economic interest in earth's crust. Ore reserves are those part of Resources for which grade and tonnage have been established with reasonable assurance by sub-surface sampling techniques and it can be mined profitably using current technology.
