Investigations into technical aspects of the Sarcheshmeh Copper Complex of Iran, with emphasis on the blasting opperations

Sarcheshmeh Copper Mine is the largest copper producer in the country, and one of the major producers in the world market. The mine covers an area of 2300 x1612m, and is located in 160 km of Keman, a southern province in Iran. About 80.000 tons of mineralized rocks are prouced everyday by blasting operations, out of which 40,000 tons are copper sulfide . The rocks are transferred to a concentrator where the useful minerals are recoverd and concentrated. This paper presents not only a thorough technical investigation of the present situation of the Sarcheshmeh Copper Complex, but also the results obtained from blasting operations in the mine, calculted with many different methods. Major problems related to the blasting operations are identified, and various approaches to solving them suggested. It is believed that applying the blasting recommendations made in this paper could cause significant improvements in the production level of this mine.
