Open pit mining is one of mankind's greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit.

Mine planning deals with the correct selection and coordinated operation of all the sub -systems, eg. mine production capacity, workforce numbers, equipment selection, budgeting, scheduling and rehabilitation. Mine design is the appropriate engineering design of all the sub-systems in the overall mine structure, e.g. production and near-wall ...

The regulatory codes related to pit slopes vary significantly around the world. In some cases there are general directives, such as for a "Duty of Care" on the part of mine management for all aspects of the operation, including the stability of pit slopes, or a requirement for "clean benches and stable faces" above the mining operation.

Open-pit mining at the Lihir Gold Mine commenced in mid-1997. The rock and groundwater temperatures range from 60 to 200°C. Dewatering is required for safe and efficient mining conditions and pit wall stability. The total drawdown required during the mine life is 200m, with over half of the drawdown required in the first 3 years.

Mining in the open pit is undertaken on 10 meter high benches. When the material is too hard to be free dug, the rock is drilled and blasted with a range of drill patterns to suit the litholog. The Open Pit is a conventional truck and shovel …

Agnico Eagle Mines (TSX: AEM; NYSE: AEM) is well on its way to growing open pit resources at its already sizeable Detour Lake gold mine 300 km northeast of Timmins, Ont., with drill results returning some impressive high-grade intervals at the future West pit.. The new drill hole results expand mineralization beyond the last resource estimate in mid-year 2021.

open pit equipment in large numbers, thus reducing production costs even further. Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use

Key words: Open pit mining, bench height, multi-criteria decision making. INTRODUCTION As a definition in open pit mining, bench height is the vertical distance between crest and toe of the bench (Fourie and Dohm, 1992). Determination of optimum bench height is a major concern in most open pit mines.

Mining operations are scheduled for 365 days per year with a 15% decrease in the production rate during the rainy season, December through March. Vertical advance is limited to two operating benches per pit phase. This will involve the movement of an average of 38.5 Mt/a of material to sustain processing of 3.5 Mt/a.

Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation's energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.
