METHOD FOR FORMATION OF COMPENSATION SPACE IN STOPE IN UNDERGROUND DEVELOPMENT OF ORE DEPOSITS

摘要

A method for formation of compensation space in stope in underground development of ore deposits includes development of air and drill workings at the level of bells, with drilling blast holes, breakage of ore rock, ore drawing with the formation of open compensation space. In the stope (panel) over the level of bells the crosscutting is carried out. From the drill crosscut upward fans of blast holes or wells are drilled with formation over sill crosscut of contours of triangular compensation space. The fans of blast holes or wells are broken with broken ore drawing through drawing working with formation in such a way of open compensation space as a triangular prism.
