Single ore particles of various sizes were broken in an impact-breakage device at varying levels of impact is shown that an optimum impact energy can be determined for the breakage of an. All the available inventions and patents focused on the principle of the rock breaking methods, i.e., different approaches are used to answer the basic question of how to break a rock mass. In terms of the application of the non-explosive technology, we need to quantify. Jan 27,  · Current methods of mechanical excavation of rock are limited in regard to the material which can be extracted economically. The use of roadheaders with pick tools has the advantage of high flexibility in form of turn off radii down to 1 m but is limited by rock strength to figures below MPa UCS. While mechanical rock excavation machines with disc cutters can handle rock strengths above Cited by: 3.
