METHOD OF WORKING TRENCH DIRECT DRIVING Russian patent published in 2016 - IPC E21C41/26 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be implemented at open development of mineral deposits by non-transport system in complicated mining and geological conditions. Method involves performing stripping operations by longitudinal stripping cuts by direct system with laying of overburden rock by inclined layers into external dump, arranged on idle open pit wall upper platform, with overburden rock stockpiling into external dump by longitudinal dump embankments with upper working platforms, which are formed by dumping front. At that, dumping front is moved in transverse direction from external dumping external side to its inner side, external dump outer side is formed with longitudinal final embankments upper working platforms, and external dump inner side is dumped by overburden rocks solid slant.
