Surface mining is also know as, Open pit, Open cast and Strip Mining. Sump should be located at the bottom of the Mine . Height and width of the bench . Drilling and blasting . METHOD OF SURFACE MINING INCLUDES. Openpit mining : Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using one or more horizontal benches.
SURFACE MINING ≠ STRIP MINING: Although sometimes mistakenly referred to as strip mining, oil sands is actually mined from an openpit below several meters of overburden. Strip mining is the mining of a relatively flat deposit very close to the surface, commonly used in coal or phosphate industries.

Mining techniques can be divided into two common excavation types: surface mining and subsurface (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.
Limestone, dolomite, and marble the carbonate rocks are the principal karstforming rocks. Karst is a type of topography that is formed on limestone, gypsum, and other rocks by dissolution that is characterized by sinkholes, caves, and underground drainage regions. Karst areas constitute about 10 percent of the land surface of the world (ﬁ g.
Mining parameters in a surface mine are influenced by strata conditions and their subsequent design for actual mining process. The structural aspects of overburden and floor material play a significant role in the predictive behavior of rock masses in response to the mining operations, especially of
Jan 31, 2019· The results show that the groundsurface in the mining areas experienced three collapse processes: karst collapse, mixed collapse, and mininginduced collapse. Karstcollapse sinkholes were found during the construction stage of the mine and are generally formed in the marble part of the marble–granite contact zone.

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.
Mining of marble or, for that matter, any dimension stone is different from conventional mining practic In conventional mining method, mined out minerals are obtained in smallsize fractions whereas in dimension stone mining, largesize intact blocks without minor cracks or damages are extracted
