STUDY OF TECHNICAL SOLUTIONS TO STRENGTHEN THE LINING OF THE BARREL IN THE ZONE OF INFLUENCE OF CONSTRUCTION NEAR-WELLBORE PRODUCTION

The present study considered technological schemes of construction tree trunks workings of vertical shafts. Analyzed studies in the evaluation of the stress-strain state of mining and development of solutions to improve their sustainability. The technique of numerical simulation of the vertical shaft, the input data and characteristics of the materials. Perform step numerical modeling portion of the barrel in the construction zone near-wellbore production. Analyzed the data and the main regularities of stress-strain state of the lining of the trunk. The efficiency gain by bolting the barrel device reinforcing layer of high-strength carbon-fiber laminate. The dependence of the bearing capacity of the lining of the reinforcement ratio and sets out the scope of the solution. Developed a method to determine the required percentage of reinforcement for strengthening concrete lining vertical shafts. Conclusions are based on research findings.
