titleOfInvention | Process for mining semicircular to circular mining fields in wet extraction |
abstract | The invention relates to a method of wet extraction with periodic change of a working face by swivelling about an angle of slew for working raw materials and for laying out open, water-filled excavations on a larger scale. The aim of the invention is to reduce the capital expenditure and the operating costs during the wet extraction and to reduce the stock losses during the working of the raw materials. According to the invention, a transport means which travels on land and interacts with a floating dredge, a floating conveyor chain and a water-land transfer apparatus is shifted by an angle of slew in several steps of the method in accordance with the face advance. In addition, a channel is excavated at the end of the working level for each new working area. The working areas are worked in each case only in one direction of advance. |
