Non-explosion development of limestone by using continuous miners

A non-explosion technology is proposed for opencast excavation of minerals with quarry combine miners. The method combines cutting the solid mass, obtaining a piece sized about 50 mm and loading. The miners` parameters are provided, as well as examples of their application in quarries of cement plants.
