摘要： A method useful in the continuous ore extraction in underground works intended for the permanent production of extraction from draw points or trenches, comprising the construction of reduced size drifts (4) wherein through the center defined by a group of drifts crosses a drift (2) which is intended for ore haulage, such drift crosses successively all drift groups defined at the exploitation face,—such extraction points (11) are arranged to form a regular layout [m4] at certain distances which are compatible with an interactive gravitational flow; once such drifts, trenches and haulage drifts are constructed the pre-conditioning, caving and extraction stages are carried out.

摘要： This invention leads to the creation of an apparatus for the maintenance of semiautogenous grinding mills used in the great mining field. Specifically the invention deals with an apparatus for cold cutting nuts which has a mobile cutting tool and a fixed cutting tool, in which such apparatus is driven by means of a hydraulic force, it is structured by a frontal body, a rear body and a hydraulic cylindrical chamber positioned between both bodies. Furthermore, this tool can be incorporated to a control manipulation or remote station for its easy operation.
