The optimal pit opening position and pit development determined by the Method of uniformed ratio. Key words: open surface pit, optimal point of opening, development, contemporary methods. Introduction
Claim Location. The principal provisions of the 1872 statute are: 1. After discovery of a lode or vein, a mining claim may be located on a plot of land not ex ceeding 1,500 feet in length along the lode or vein and 300 feet on each side of the middle of such vein at the surface (fig. 1).
and wire is made from the Copper Coils. It takes a lot of work to get from the Minerals in the rocks in the Copper Mine to the Copper wire bringing electricity to the clock. from a Coal fired Power Plant made out of Concrete and Steel. Over 40% of all electricity used in USA comes from Coal Fired Power Plants.
Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .
Open pit mining or strip mining is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.
and search for an adaptive rule applicable to open pit mines. For this purpose, a stochastic truck dispatching and production simulation program is developed for a medium size open pit mine consisting of several production faces and a single dump site using GPSS/H software. Eight basic rules are modeled in separate program files.

pit is filled with recycled lagoon supernatant. The pit is typically emptied every 5 to 7 days. The manure is loaded into a lagoon or storage pond by gravity through a 6 to 8 inch pipe. The objectives of this chapter are to: (1) describe the concepts used to size treatment lagoons and
This research shows that the effect of earthquakes on open pit mines cannot be ignored due to the limited number of endured open pit mines in the vicinity of strong earthquakes. However, site characteristics of pit slopes make them less likely to fail compared to natural slopes and tailing dams.

E) GENETIC ALGORITHM (GA) Firstly, Denby and Scholfield (1994) employed Genetic Algorithm (GA) as a optimization tool in open pit design [35].This technique was established on the basis of a selftraining GA and concurrently supplies a combined pit limit and extraction schedule that intends to maximize the net present value (NPV) of the production.
present in the pit (Fig. 1). Since the mineralized body is small and steeply dipping, profitability of the mine is largely dependent on the steepest possible final slope angle. Earlier, the open pit was designed with 45° overall slope angle. Therefore, the mine management sought the study for .
Optimum pit design plays a major role in all stages of the life of an open pit: at the feasibility study stage when there is a need to produce a wholeoflife pit design; at the operating phase when pits need to be developed to respond to changes in metal prices, costs, ore reserves, and wall slopes; and towards the end of a mine's life where ...
