【 摘 要 】

The historical background is presented, and the experience gained in application of equipment and technologies of underground placer mining in Yakutia is considered. The variant of chamber mining with application of bolter miners and backfilling self-propelling machinery is proposed. The variant allows increase in productivity of development heading and actual extraction by 4-5 and 2.5 times, respectively, and reduces mineral loss and dilution.
