Borshevskiy S. Physics-technical and organizational bases of the intensive technologies of the vertical shafts building in the increased water content of the rock massif

The dissertation is devoted to the working out of physics-technical and organ-izational bases of the intensive technologies of the vertical shafts building in the in-creased water content of the rock massif, which supplied with rising of the excava-tion's speed, economy and reliability of their exploitation. The exploring of the ten-dency of the shaft building technology and periodization of their building on the basic of technically-economical index with the taking water content into account. On the bases of inrush fixture against water contents and forming of the geoactive zones in aquifer with building value taking into account, grounded scientific-technical princi-ples of rising of shafts' steadiness due to smolization of the strained water content rocks and creation of hard water-resist stable concrete support by the way of inserting water-resist additions into the concrete and its surface handling with penetrational matter. The mechanisms of the system behavior "concrete support - water content rock massif" with the help of the computer modeling of the support interaction with the aquifer were researched here. The technological regulations of the vertical shafts building progressive operations in water content and strengthening conditions which supplied the rising of shaft building and its lower class transforming with minimal building value and efficient constructive actions where grounded. The package of active control of aquifer deflected mode and inflow organiza-tion in shafts for guaranteeing it's long-lasting stability was developed on the base of received dependences.
