Abstract

The invention discloses an underground chamber whole-section deformation automatic monitoring device and a method involved in the device. The underground chamber whole-section deformation automatic monitoring device comprises an angle measurement mechanism and a distance measurement mechanism. The angle measurement mechanism is provided with a pointer, a dial, a gradienter, a base and a fixing hole. The distance measurement mechanism is provided with a rotary body, a bearing, a rotary rod, a fixing nut, a laser probe and a displayer. Through efficient coordination of the angle measurement mechanism and the distance measurement mechanism, deformation of any point of the chamber section, the over-excavated volume and the excavated volume of the chamber section at the monitoring point and the supporting thickness of a gunite layer of a chamber can be measured, and the purpose that deformation of each portion of the chamber is accurately, efficiently and rapidly measured is achieved.

Description

technical field [0001] The invention relates to an automatic monitoring device for full-section deformation of an underground chamber and a method for applying the device. Background technique [0002] The chamber is an important transportation channel for underground mines, and its stability is one of the key factors that determine whether the mine can be safely produced. Chambers with different uses, locations, and surrounding rock environments have different stability, resulting in varying amounts of deformation. same. There are many methods for monitoring chamber deformation, such as chamber surface convergence meter, multi-point position meter, etc. However, the above methods all have the disadvantages of cumbersome on-site construction procedures, low accuracy, time-consuming monitoring, and short-term monitoring instruments. Based on the above situation, there is an urgent need for a better full-section deformation monitoring device of the chamber to achieve the pur...
