FIELD: mining engineering. SUBSTANCE: method involves building up enclosing dams within the washed-in card contour, setting vertical carriers on the card base, on which horizontal grilles are fixed covering the whole area taken by the card and having draining layer made of cartridges and lumpy sorbent all over the grilles. Rock mass is washed in over the draining layer. Air is sucked off from the cavity under the rock mass creating rarefaction zone under the rock mass. Plants with short vegetation period retaining moisture are cultivated on the massif surface in the warm year seasons. Working agent like warm air is pumped under the massif to provide marketable state of the massif with respect to its moisture contents, to intensify moisture transfer of the massif and to promote massif processing in case of derivatives bioproducing. EFFECT: enhanced effectiveness of rock desiccation. 3 cl, 1 dwg
