METHOD FOR COMPREHENSIVE DEVELOPMENT OF COMPLEX ORE FIELDS

摘要

FIELD: mining.;SUBSTANCE: method includes the subterranean development of field with use of the chamber systems with the solid stowing and following refinement of the ore mass at the ore mill in the following stages. At the beginning, the ore recovering from the first-stage chamber (4) is performed. The ore pickings from the first-stage chamber (4) are processed to concentrate and final tailings. The tailings are processed to pellets. From the pellets, two workflows are formed, the first pellet flow is exposed to the heap leaching, and the second pellet flow is conditioned until the required mechanical characteristics. On completion of the leaching process, the pellets of the first workflow are mixed with binding agent and water, to receive the fill mixture, the fill mixture is sent to the first-stage chambers (4) until filling; after the fill mixture is solidified, the ore recovering from the second-stage chamber (5) is performed, the chamber's bottom is strengthened and prepared with the solidifying mixture which is prepared using the waste from the heap leaching; pellets of the second workflow are sent to the chamber with their following subterranean leaching.;EFFECT: comprehensive and complex development of minerals and ecologic-economic effects are provided.;4 cl, 1 dwg
