Surface mining. Surface mining is exactly what the word says digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining.3.3 Crushing of rock and minerals Crushing is the largest process operation in minerals processing. Surface mining systems are different for different type of deposits. The paper is concern.Site consisted of one surface pit and ac companying rock processing facilities that mine and process approximate ly 1.13 Mt (1.25 million st) annually of crushed stone and lime products. Mining consists of bench drilling and blasting (by a contractor), and mining the limestone rock.The blasted rock is mined using front end loaders (FELs).An Analysis and Prevention of Flyrock Accidents in Surface Blasting Operations by T. S. Bajpayee, Harry C. Verakis, and Thomas E. Lobb Abstract Blasting is a primary means of extracting minerals and ores at surface mining operations. The domestic consumption of explosives and blasting agents during the year 2002 was about 5.53 billion pounds.
