Divided into two volumes, this accessible work describes the principles involved in hard rock blasting as applied to open pit mines. A large number of examples illustrate the application of the principles. The first volume introduces basic engineering concepts and the building blocks that make up a blast design.

In the buffer hole design concept the placement of the buffer holes determines the designed perimeter and the demand on the perimeter holes is substantially reduced. Perimeter charging options for the buffer design concept will require decoupling.

and it generalizes the concept of underground and openpit mining as part of a capacitated network. This allows representing any form of mining as a process in the production chain, including the transition from openpit to underground operations. It establishes the complexity of the mining problem for both underground and open pit.

5 OVERALL PIT SLOPE ANGLE: The angle measured from the bottom bench toe to the top bench crest. It is the angle at which the wall of an open pit stands and it is determined by rock strength, geologic structures and water conditions. Terminology

Oct 16, 2017· Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. Open pit Reclamation after completion Open cast Reclamation during mining open pit ge...

Basic and Detailed Engineering As a mine project progresses through the feasibility study stage, some aspects of the project might need to be designed at a basic or detailed level to further progress the project through various stages of development or to improve the accuracy of the capital cost estimate.

open pit mining operations along with several alternatives to assess the validity of its results. As a result, three metrics are proposed to evaluate the performance of the emissions control programs implemented in open pit mines. The methodology was applied to 7 of the 8 open pit coal mining companies operating in Colombia. A description of

method into pit optimisation software that takes into account the value that ore has if mined by underground method. Consider a case in which some blocks can be mined by either open pit or underground method. For any such block, the value used for pit optimisation must be the difference between its open pit value and its underground value.

Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden.
