One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. We refer to this problem as the equipment selection problem (ESP). In this paper, we describe the ESP in the context of surface mining and discuss related problems and applications.

mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines . In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
Mining is a very capital-intensive industry, and it is known fact that the equipment utilization and accurate estimation is very important. Presently in India 70-80% production of minerals comes from the surface mines. In a surface mining operation, materials handling system is composed of loading, hauling and dumping.

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
Notes on Mining Method Selection. UBC Mining Method Selection is a modified version of the Nicholas approach for selection of mining method based on orebody characteristice (refer Nicholas 1981). Selection involves summation and ranking of numerical values associated with orebody characteristics that reflect the suitability of a particular method.
Equipment selection in mining engineering is one of the most important decision that is affected the mine design, production planning and economic parameters in open pit mining.

Key words: Equipment Selection, Surface Mining, Shovel-Truck Productivity, Mining Method Selection, Multi-Commodity Network Flow 1. Introduction In the surface mining application, the Equipment Selection Problem (ESP) addresses the selection of truck and loader eets to move mined material, including both waste and ore. The mining
is the only mining equipment manufacturer to offer every type of loading tool for surface mining – electric rope shovels, hydraulic front shovels, hydraulic backhoes, and wheel loaders. This guide presents an overview of these tools and describes how to use each type most effectively.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Equipment Selection for Surface Mining: A Review. Equipment Selection for Surface Mining: are several methods of surface mining, is a complicating characteristic of surface mining equipment selection,
Under similar conditions, surface mining is generally regarded to be more advantageous than underground mining. In the selection between surface and underground exploitation methods, there are a number of most significant factors must be briefly

Mining equipment selection. The selection of mining equipment is a function of the mine plan. Some of the factors considered in the selection of mine equipment include the topography of the pit and surrounding area, the amount of ore to be mined, the speed and distance the ore must be transported for processing and the estimated mine life ...

productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.
Principal considerations in the selection of surface mining and reclamation techniques and equipment include the thickness and character of the overburden, the dip of the seam, the thickness and number of recov-erable seams, and the physical and chemical characteristics of the coal. The three surface mining techniques most widely used in the

Optimum equipment and method selection for high selective excavation at SLE Identification of main factors related to equipment selection Firstly, three priority degrees of effective parameters were determined according to the mining and geological conditions in order to select optimum machinery and mining methods.
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface.
In the surface mining industry the equipment selection problem involves choosing a eet of trucks and loaders that have the capacity to move the materials speci ed in the mine plan. The optimisation problem is to select these eets such that the overall cost of materials handling is minimised. The scale of operations is such that although
The course will cover various types of material handling methods and equipment including continuous and cyclic loading and transportation systems. The course will review surface mining equipment including loaders, shovels, draglines, trucks, rail, dozers and scrapers.
The selection is based on technical and environmental aspects and surface mining is preferred to extract the minerals from the surface area. As compared to underground mining this method of mining removes soil and rock overlying the mineral deposit.
