Different repair and reinforcement method based on classification of well wall rupture degree

Abstract

The invention discloses a different repair and reinforcement method based on classification of a well wall rupture degree. The method comprises the steps of classifying the rupture degree of the wellwall according to the rupture range and the rupture depth of the well wall; and then adopting a corresponding repair and reinforcement method according to different well wall rupture degrees. According to the method, the different repair and reinforcement method covers repairing construction methods of different crack degrees and depths of the well wall from surface cracks to the deep hollowing, the limitation of a single well wall construction repairing process is broken through, and the urgent need for a sudden comprehensive treatment plan in the field of vertical shaft repairing is met. Themethod has the advantages of safety and reliability, short construction period, practicality and high efficiency.

Description

technical field [0001] The invention relates to the field of mine construction, in particular to a different repair and reinforcement method based on the classification of shaft wall rupture degree. Background technique [0002] With the increasing demand for mineral resources in our country, the mineral resources that are easy to mine in the shallow area are becoming increasingly exhausted, and the mine is deepened at an average rate of 8-12 m per year. After entering the deep part, there are more uncertain factors that cause shaft wall rupture. , and then induce different degrees of shaft wall rupture. The vertical shaft is used as a throat project for lifting and transporting coal (or gangue), transporting personnel, materials and equipment, as well as ventilation and drainage during mine production. Once the shaft wall is broken, it will greatly limit the lifting capacity of the shaft, and there will be many safety hazards, and even Lead to the occurrence of some safety...

AI Technical Summary

Problems solved by technology

[0004] In recent years, there have been many problems in the treatment of fractured shaft walls of vertical shafts. Due to the lack of deep understanding of the limitations and advantages of each method for repairing shaft wall fractures, problems such as improper selection of repair methods and incomplete formulation of support schemes have resulted. The blindness and inefficiency of on-site construction also indirectly affected the treatment effect and caused unnecessary economic losses.
