The most common surface mining methods such as strip mining, open pit mining, opencast mining and quarrying start from the earth''s surface and keep exposure to the surface during the extraction period. Disruption of the surface significantly affects the soil, fauna, flora and surface water, thereby influencing all types of land use.

any of the two methods of mining i.e., surface mining methods and underground mining methods. Surface mining operations can be classified into open pit, opencast, strip, alluvial and insitu mining, depending on method of mining being considered (Hartman, 1987).

Coal MiningMethods. Mining Methods Coal is mined by two main methods surface or opencast mining and underground mining.. The choice of method is largely determined by the geology of the coal deposit the majority of the world''s coal reserves are recoverable by underground mining. The method used is determined by the depth of coal deposit and the overburden over it.

OBJECTIVES—To answer the question whether living near opencast coal mining sites affects acute and chronic respiratory health. METHODS—All 4860 children aged 111 from five socioeconomically matched pairs of communities close to active opencast sites and control sites away from them were selected.Exposure was assessed by concentrations of particulate matter with aerodynamic diameter

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
Conventional Methods of Surface Mining. Openpit mining and strip mining are the two major egories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the loion of the ore body and the mode of mechanical extraction.

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which
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.
