The mining activity that has developed in the NascaOcona belt has largely been by artesanal methods although there are some more modern mines in the area. There exist also mining formal activities of iron and copper. Artesanal mining is characterized by its labor intensity and lack of modern mining equipment.
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 consider a loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.

The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of
Motor graders are heavy equipment used for fine grading and for moving small amounts of dirt. They have a long blade that can be adjusted to meet certain angles to create a flat surface. They can also be fitted with a second blade in front of the front axle and in some instances can be used for underground mining.
Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion.
It''s also equipment which is very easy to use and being on wheels, with a tight turning range, is the best choice for smaller sites. Skid steel loaders help lower soil compaction, work well in difficult conditions such as snow/mud, and have a limited impact on finished zones because of their tread system.
