METHOD OF WELL SHAFT CONSTRUCTION, SHAFT SINKING COMBINE, ROCK DESTRUCTION UNIT AND REINFORCING SUPPORT ERECTION DEVICE (VERSIONS) Russian patent published in 2016 - IPC E21D1/03 E21D5/12 

FIELD: mining.

SUBSTANCE: invention relates to mining, namely, to construction of mining plants vertical shafts and shaft-sinking and tunnelling equipment for its implementation. In compliance with structure of shaft each stage of working face development in depth and removal of broken rock is independent of reinforcing support assembly and installation stages. Development of face and removal of broken rock are carried out simultaneously and separately in technologically independent zones during whole process of development. Between each stage of working face development in depth and removal of broken rock and appropriate assembly and erection of reinforcing support step power reserve of process equipment is maintained in form of developed in depth bottom hole and/or clearance to form next step of reinforcing support assembly and erection in extent of at least one step of reinforcing support erection. At that, power reserve of process equipment is achieved due to mounting frame equipment with support jacks, which can interact with bottom frame. Shaft sinking combine comprises rock destruction unit mounted on bottom hole frame for development of face and loading of broken rock and located above it device of reinforcing support erection, including mounting frame, that is located relative to bottom frame with possibility of converging in operation, excluding their physical contact. In rock-breaking unit downhole frame comprises rotary base and in its lower part is equipped with located along perimeter and directed downwards support jacks with independent working drives. Rotary base on side opposite to location of journal with rock cutting tool comprises through opening, equipped with rotary bracket, on which loading unit with jackknife boom and bucket is fixed. At that, boom is configured with possibility to output bucket beyond bottom frame during any position of rotary base. Rotary support of loading tool is located in center of rotary base, and rock cutting and loading tools are made with possibility to develop face and removal of broken rock simultaneously and separately in technologically independent areas during whole process of development. In first version of reinforcing support erection device mounting frame comprises rotary shelf, in middle part of which there is rotary bracket with jackknife boom with tip. At that, boom reach is configured with possibility to output tip beyond mounting frame at any position of rotary bracket, wherein mounting frame in its lower part includes downwards directed support jacks located along perimeter, made with possibility of simultaneous stepwise displacement, or in its upper part comprises fasteners of traction winches suspended ropes. In second version of reinforcing support erection device mounting frame has stationary shelf and in its lower part is equipped with located along perimeter and directed downwards support jacks.

EFFECT: inventions increase speed of vertical shafts tunneling and stabilize quality of reinforcing (waterproofing) tubing and/or concrete support erection.
