FIELD: construction. SUBSTANCE: complex of structures includes located under storage - service drift, slot spaces and water-proof layers. Complex has a row of drain holes containing draining pipes. Holes are communicated with day surface, located at acute angle to vertical axis of drift and connected with the latter. Water-proof layer is located around draining pipes. Slot spaces are made under sealing layer. Method for making complex structures includes three phases of construction. Made in the first phase are service drift and draining holes. During the second phase, pressed through draining holes is sealing material into rocks round casings of holes. During the third phase, slot spaces are made and sealing fill is introduced into them. Broken rock resulting from driving slot spaces is taken to the surface through service drift. EFFECT: higher efficiency. 9 cl, 10 dwg
