Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job. For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.

Openpit mining is a surfacemining operation, in which rocks or minerals are extracted from the Earth by creating an open hole, or pit, in the Earth's surface. These pits are generally 1km deep beneath the Earth's surface, and are used to exploit lowgrade ore bodies.
Conversely, there are disadvantages of an underground expansion into the South Area. Firstly, the orebody will be mined by the open pit at some stage in the project life. Hence, ore blocks mined from underground will incur both an underground mining cost and an open pit mining cost.
In this article, we explore the impact of adapting Automated Haulage Systems (AHS) to a typical open pit mine considering the initial investment, rampup delays, impacts of operating costs ...
The mining operation is conducted using a large fleet of conventional open pit mining equipment comprising blast hole drilling rigs, electric face shovels, and 170t and 190t offhighway trucks supported by appropriate ancillary mining equipment.
As is typical of openpit mining, the Morenci operation has miles of benches circling each gigantic excavation. The benching allows the holes to be stairstepped into the ground one level at a time.
Openpit mining 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. The
