Deep well ingate device with deformation measuring function and use method

Abstract

The invention discloses a deep well ingate device with a deformation measuring function and a use method. The deep well ingate device comprises a plurality of ingate supports and an iron wire, the ingate supports are arranged side by side, and the two ends of the iron wire are horizontally fixed to a rock mass through embedded steel nails. Each ingate support comprises a top beam, a bottom beam, a left supporting column and a right supporting column, the left supporting column and the right supporting column are arranged between the top beam and the bottom beam in a mutually parallel mode, and the top beam is fixedly connected with the bottom beam through the left supporting column and the right supporting column. Each top beam comprises top beam inner I-steel and top beam outer I shaped steel, each top beam inner I shaped steel is fixedly connected with the corresponding top beam outer I shaped steel through a plurality of top beam web members, and a two-way digital scale is fixedly arranged on the lower portion of the top beam inner I shaped steel. The deep well ingate device is high in supporting intensity and high in adaptive capacity of surrounding rock deformation, a deformation monitoring device is arranged, so that the recoverability is good after the use of the device is completed, and the subsequent recycling is convenient to achieve.

Description

technical field [0001] The invention relates to a deep well support device and a use method, in particular to a deep well horse head door device with a deformation measurement function and a use method. Background technique [0002] Deep mines are characterized by complex engineering geological conditions, high ground pressure, and difficult roadway maintenance. Therefore, the stability control of surrounding rocks in deep roadways has become a major problem in the mining industry. Among them, the Matou gate of the deep shaft is located at the throat of the mine, and the design section is large. During the construction process, the surrounding rock is repeatedly disturbed, and the rheology of the deep surrounding rock is significant. Therefore, the Matou gate of the deep shaft is often damaged and unstable. occur, seriously affecting the stability of surrounding rock and the safety of supporting structures. [0003] In order to solve the problem of stability control of the ...

Problems solved by technology

However, the existing supporting devices still have many limitations

First, the supporting structure provided by the supporting structure is insufficient in strength, low in stiffness, and poor in adapting to surrounding rock deformation; second, the measurement of surrounding rock deformation must be equipped with a complex and expensive monitoring system, and the supporting structure itself is not simple. measuring device; thirdly, the construction process of the support structure is complicated, and it is necessary to carry out primary support, secondary support, or even three or more times of support, and the roadway maintenance efficiency is low and the cost is high; fourthly, the support body, support Low recyclability of protective elements

It can be seen that the current deep mine horse head gate support structure has relatively large defects in terms of safety, effectiveness, and economy, which seriously affects the mine transportation and lifting operations, and hinders the development of intrinsically safe and efficient green mines. The construction process has also become one of the restrictive factors for the current construction of large modern mines
