Abstract

The invention provides a mining tunnel deformation monitoring device, solving the problems that the conventional tunnel monitoring is bad in monitoring effect, inconvenient to observe the construction, and complex in installation. A wire rope is arranged between two basic points, a lower fixing seat is provided with two vertically distributed telescoping rods, left and right spiral rods are arranged between the two telescoping rods, a spring sleeve is arranged above the upper telescoping rod, a telescoping spring is arranged in the spring sleeve, the upper end of the spring sleeve is provided with a spring precompressed cap, the lower end of the upper fixing seat is provided with vertically distributed lengthening extension rods and a scale rod having the lower end tightly attached to the telescoping spring, the lengthening extension rods are in threaded connection with the scale rod via an upper connecting sleeve, and the spring sleeve is provided with a scale pointer and a level pointing to the scale rod. The mining tunnel deformation monitoring device is suitable for measuring the deformation amount of tunnels in different heights, is visual and convenient for observation and recording, and meanwhile, the construction boring is not needed, the installation is convenient, the on-site construction progress is not influenced, and the repeated use can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of mine roadway construction, in particular to a mining roadway deformation monitoring device. Background technique [0002] Roadway surface displacement monitoring is the basic content of roadway mine pressure monitoring. Roadway surface displacement mainly includes roof and floor displacement, roof sinking, bottom heave and two-side displacement. Among them, roof sinking is the most concerned by mine management personnel. monitoring project. [0003] At present, various types of roof abscission instruments are mainly used for monitoring. A 5-10m drill hole is constructed on the roof, and two deep and shallow base points are arranged in the drill hole. There are mainly the following problems in the process of installing and using the roof delamination instrument on site: [0004] 1. The measuring cylinder of the roof delamination instrument is installed on the roadway roof, which is not convenient for dri...
