Abstract

The invention discloses an ultrasonic roadway surface convergence analyzer. The ultrasonic roadway surface convergence analyzer comprises an installing pole, an instrument cabin, a left ultrasonic transceiving transducer, a right ultrasonic transceiving transducer, a lower ultrasonic transceiving transducer and other parts. The analyzer is fixed to a top plate and a bottom plate of a mine roadway or the two sides of the mine roadway through the installation pole. After initialization, the shape and dimensions of the initial section of the mine roadway are recorded, so that an initial image of the section of the roadway is obtained; after the analyzer enters a normal working state, the left ultrasonic transceiving transducer, the right ultrasonic transceiving transducer and the lower ultrasonic transceiving transducer are started according to set time, ultrasonic signals are emitted to the top plate, the bottom plate and the two sides of the roadway and are collected, and the collected ultrasonic composite echo signals are processed through a processor, so that a composite image of the section of the roadway is obtained, wherein compared with the initial image, the deformation and convergence amount of the top plate, the bottom plate and the two sides of the roadway are obtained. The ultrasonic roadway surface convergence analyzer is easy to install, stable and reliable in measurement and capable of achieving non-contact online monitoring of the convergence amount of the whole section of the top plate, the bottom plate and the two sides of the mine roadway, thereby providing online monitoring data of the convergence amount of the whole section for the special project of the mine roadway surface convergence amount.

Description

technical field [0001] The invention belongs to the technical category of dynamic special monitoring of the surrounding rock of a mine roadway in a coal measure stratum, and in particular relates to an ultrasonic roadway surface convergence analyzer for non-contact online monitoring of the full-section convergence of the roadway. Background technique [0002] In the design of mine roadway support, the monitoring of roadway surface convergence is a main content in the special monitoring of roadway surrounding rock dynamics. The convergence amount is mainly the relative approach of the roadway roof, floor and two sides, and the roadway surface convergence measuring station is usually installed by the cross point method, and a measuring station is arranged at an interval of 50~100m along the axial direction of the roadway, and each measuring station is arranged with two There are two measurement sections, and the interval between two measurement sections is 1.5~3.0m. At presen...
