Problems solved by technology
However, the depth of the general roadway can reach more than 1000 meters, and the internal space of the roadway is not large, which causes inconvenience to the transportation, installation and storage of the corresponding detection device.
[0004] Temporary support is generally carried out before the permanent support of the roadway. If temporary support is adopted, it will generally affect the detection of data such as roadway rock burst and rock burst.

The invention discloses a mine support capable of monitoring rock burst in real time. The mine support can detect the rock burst or impact the ground pressure while supporting a roadway and comprises a supporting leg assembly and a support assembly. A pressure sensor is arranged on the supporting leg assembly, and the rock burst of the roadway can be monitored in real time through the pressure sensor. Various energy absorbing and receding structures are arranged on the support assembly and the supporting leg assembly, instant energy absorption and timely receding on the rock burst can be achieved, and the impact resistance of the support is improved. According to the mine support, the instant impact force of the pressure sensor can be adjusted easily and conveniently, and the pressure sensor can be effectively protected. The pressure sensor is easy and convenient to replace, the maintenance cost in the using process is greatly reduced, and the difficulty is greatly lowered. According to the mine support, the rock burst is detected in real time through the pressure sensor, the precision is higher, and the reliability and durability are superior to those of an existing rock burst detecting device.
Description
technical field [0001] The invention relates to a mine support, in particular to a mine support capable of real-time monitoring of rock burst. Background technique [0002] In the process of underground coal mining, it is generally necessary to drill a roadway first, and then carry out coal mining from the roadway. The roadway needs to be supported, and the current mainstream method is to use anchor rods, anchor cables, U-shaped brackets, etc. for permanent support. However, due to the complex geological conditions of the underground, and the different rock bursts, soil properties, and rock formations in different geological sections, it is necessary to carry out adaptive design of the roadway support scheme according to the geological conditions of each section of the roadway, which requires Before the permanent support is carried out, the roof pressure and rock burst of the roadway are monitored to serve as the data basis for the permanent support design scheme. [0003]...
