3 surface mining isype of mining in which soil and rock overlying the mineral deposit the overburden are removed. surface mining is the predominant exploitation method worldwide. surface mining requires large capital investment primarily expensive transportation equipment, but generally results in high productivity i.e., high output rate of ore.
9.05.1.2.1 mine workings and open pits. minerals are typically excavated by underground mining, strip mining, or openpit mining. the selection of the mine design is dictated by the physical structure and value of the ore body and by the characteristics of the adjacent geological materials.

Bins, hoppers, and feeders are types of equipment used to help regulate the flow of material through the mining process. bins and hoppers are containers with open tops for material to enter and an opening at the bottom for material to exit, typically over a.
Constructed especially for the tough operating conditions encountered in open cast mining, surface miners extract primary resources such as coal, gypsum, rock salt, phosphate, bauxite, or limestone with unconfined compressive strengths of up to 80 mpa with high purity and maximized exploitation of deposits.
However, for largescale open pit mining in particular, the truck and loader material movement practice is the preferred method of materials handling czaplicki, 1992 ta et al., 2005. throughout this paper, we consideroader to be any type of high productivity excavating equipment, which may includeining loader, shovel or excavator.
Ifineral deposit lies close to the surface, is of sufficiently big size, surface mining an openpit mine can be the most suitable method to extract the ore whyte and cumming, 2007.
In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. there are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. these include strip mining, openpit mining, mountaintop removal, dredging and highwall mining.

Mining mining surface mining it has been estimated that more than twothirds of the worlds yearly mineral production is extracted by surface mining. there are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. these differ from one another in the mine geometries created, the techniques used, and the minerals.
Mississauga, canada sandvik mining and rock solutions has won an 18.5 mcad order for surface mining equipment from newcrest in canada that will optimize reliability and productivity. automation ready, the surface and rotary drills will be used at the open pit copper and gold mine currently in production.
Open pit mining method mine working open to the surface. funnel shaped hole in ground, with ramp spiraling down along sides, allows moderately deep ore to be reached. operation designed to extract minerals that lie close to the surface it is used when the ore body is near the surface and little overburden waste rock needs to be removed.
Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. this method is practical and costeffective when the uranium ore is located near the surface e.g., within 100 m. underground mining and isl methods may be considered for sites that have uranium ores at deeper depths.
Openpit mining, also known as opencast mining, isurface mining technique that extracts minerals from an open pit in the ground. this surface mining technique is used when mineral or ore deposits are found relatively close to the surface.

Surface mining is defined as the extraction of ore from an open pit or burrow. surface mining is sometimes known as openpit, opencut or opencast mining and is only commercially viable if the deposit is located relative close to the surface. less than 20 of albertas bitumen reserves are close enough to the surface to be mined.
Surface mining isorm of mining in which the soil and the rock covering the mineral deposits are removed. it is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to.
