FIELD: mining.
SUBSTANCE: group of inventions refers to extraction of minerals from underground deposits, particularly refers to method and system facilitating access to underground zone from ground surface. The system contains the first borehole, running from the ground surface into the underground zone, the second borehole, running from the ground surface into the underground zone, at that the second borehole crosses the first borehole in a crossing point, located in direct vicinity from the underground zone, and a well pattern, containing plurality of side boreholes, branching from the main borehole of the pattern; at that the well pattern is connected with the crossing point and serves for pumping out of fluids from underground zone into the crossing point.
EFFECT: drainage systems facilitate access to vast underground zone from surface, while well with vertical reservoir permits efficient withdrawing and/or extracting of entrained water, hydrocarbons and other minerals.
