From 1982 onwards, the Kiev cavers started systematically working in Krubera Cave, located less than 200 metres from the Kujbyshevskaja entrance, hoping to connect with the Arabikskaja System and increase its total depth by 60 m. Exploration progressed slowly because critically tight meanders between the pits required enormous amounts of work to widen them to a passable size.
