management of the line mining and deposition process at the .The open pit Mutalj is a part of the Lafarge Cement Factory of Beočin and its purpose is to supply the factory with line as one of the ore required for cement production. The required quality of the mined line is determined by the technological process of creating cement and, before all, the quali- ty of marl as the.line open mining,Economics of Underground Conversion in an Operating Line .This thesis deals with the appraisal of the economics of underground conversion in surface line mining operations. Software that predicts the time at which an open pit operation should be converted to underground extraction has been developed. The software is based on estimates of capital expenditures required for.

Most line and dolomite are mined from open quarries, although in many areas economic and environmental considerations favor large-scale production by underground mining. The only carbonate materials not consistently recovered by surface or underground mining are shell products that are dredged from parts of.

Open-pit mining - Wikipedia

Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of.
