Подледниковое озеро Восток в Антарктиде является уникальным природным объектом, всестороннее исследование которого предполагает отбор проб воды и пород донной поверхности. Для дальнейшего изучения озера необходимо бурение новой скважины доступа и разработка экологически безопасных технологий его исследования. В статье рассмотрены реализованные, а также находящиеся в стадии разработки технологии отбора проб пород донной поверхности подледниковых озер. Все рассмотренные технологии соответствуют требованиям экологической безопасности ведения работ и обеспечивают отбор проб. Авторами предложена альтернативная технология, основанная на использовании шагающего устройства и благодаря своей мобильности позволяющая произвести селективный отбор проб пород с большой площади, используя при этом только одну скважину доступа. Рассмотрены основные задачи, которые необходимо решить для реализации предложенной технологии. Материалы представлены коллективом авторов, имеющих многолетний опыт буровых работ на станции «Восток» в Антарктиде и опытно-конструкторских работ по проектированию оборудования и нестандартных средств механизации для сложных горно-геологических и климатических условий.

The subglacial Lake Vostok in Antarctic is a unique natural phenomenon, its comprehensive study involves sampling of water and bottom surface rocks. For further study of the lake, it is necessary to drill a new access well and develop environmentally safe technologies for its exploration. This article discusses existing and potential technologies for sampling bottom surface rocks of subglacial lakes. All these technologies meet environmental safety requirements and are conducive for sampling. The authors have proposed an alternative technology, using a walking device, which, due to its mobility, enables selective sampling of rocks across a large area from a single access well. The principal issues, related to the implementation of the proposed technology, are investigated within this article. This report is prepared by a team of specialists with many years of experience in drilling at the Vostok Station in Antarctic and in experimental work on the design of equipment and non-standard means of mechanization for complicated mining, geological and climatic conditions.
