FIELD: mining.SUBSTANCE: invention relates to mining industry, namely, to construction of vertical shafts of mining enterprises and shaft sinking equipment for its implementation. Shaft sinking combine consists of the rock destruction tool for mining face and body for loading of the broken rock. Device for erection of reinforcing support includes a mounting frame, in lower part of which along the perimeter the downwards support jacks with independent working drives are located, configured to interact with shaft bottom. From the side surface of the mounting frame the spacer jacks directed to the sides are located, configured to interact with shaft wall. Wherein the rock destruction tool for mining face and loading of the broken rock is mounted on the bottom frame, which is connected to the mounting frame by means of suspended jacks row located along its perimeter. Herewith the bottom frame is equipped with elements of the progressive kinematic pairs for interaction with support jacks of the device mounting frame for erection of reinforcing support, at that, the bottom frame is located relative to the mounting frame with a possibility of converging in operation process, excluding physical contact.EFFECT: increased reliability and speed of vertical shafts passing by the combine and quality stabilization of erection of reinforcing tubing and/or concrete support due to implementation of the "parallel" principle driving shaft in the process and due to combination in time and separation in area of the rock destruction process and its unloading.10 cl, 9 dwg |
