METHOD OF MINE SHAFT CONSTRUCTION AND A SHAFT-PENETRATING COMBINE Russian patent published in 2019 - IPC E21D1/03 E21D5/00 

FIELD: mining.

SUBSTANCE: group of inventions relates to mining. Method includes development of bottomhole, erection of temporary support and permanent support with backlog of working face by value not lower than level of conditional stabilization of permanent deformation of rock walls, at which load on support does not exceed current carrying capacity of support. Level of conditional stabilization is determined from the nature of change in deformation of the walls. For this purpose, at the bottom of the bottomhole at one point the conditionally initial position of the rock wall of the barrel is fixed, and as it is deepened to the specified level, the deformation of the rock wall relative to its conditionally initial position is measured, after which the pattern of deformation of walls along their height from the level of fixation of the conditionally initial position is determined. Load on the support is determined from the current value of deformation at the level of conditional stabilization of residual deformation of rock walls of the barrel proceeding from the established character of deformation of its walls. Combine comprises erection frame for erection of support and bottom frame, shield spacer shell in the form of row of installed along perimeter shandor, connected to them by means of spacer hydraulic jacks, actuator of barrel cross section processing and control system. Between one shandor and one of the frames or both frames and / or between two adjacent shandors displacement sensors are arranged. Control system includes a measurement result processing unit which forms an ordinate of the level of conventional stabilization of residual deformation of rock walls from the face bottomhole, and a control unit for the barrel cross-section processing by the actuator. As a result, reliability and safety of works on construction of mine shafts, in wide range of mining and geological conditions and specific technological features of performance of mine-penetrating works.

EFFECT: technical result consists in improvement of operating reliability of mine shaft and productivity of penetration with reduction of resource consumption of works.
