Problems solved by technology

At present, the site mainly relies on the arrangement of section measuring stations to monitor the deformation of the roadway surrounding rock. The section convergence data obtained by this method are spatially independent and cannot effectively reflect the overall deformation of the roadway surrounding rock such as roadway uplift, subsidence, and lateral movement.

Abstract

The present invention discloses a tunnel surrounding rock deformation monitoring device and method. The device comprises a measurement support, a leveling pedestal and an assistant position device. The measurement support is vertically arranged on the leveling pedestal through a channel, is able to horizontally move along the channel and is provided with a laser range finder with adjustable height and an observation target, and the assistant position device includes a support bar vertically arranged and a laser locator fixed on the support bar. The tunnel surrounding rock deformation monitoring device and method are configured to employ a laser locator to perform spatial orientation and employ a laser range finder with an adjustable height and a channel adjusting the horizontal position of the measurement support so as to realize that the origins of each measurement are all located at the same straight line in a three-dimensional space and conveniently and rapidly determine the whole deformation characteristics of the tunnel surrounding rock.

Description

technical field [0001] The invention belongs to the field of surrounding rock monitoring of mine roadway engineering, and in particular relates to a device and method for monitoring the overall deformation of roadway surrounding rock. Background technique [0002] The roadway constitutes the place and passage necessary for all activities such as underground production, transportation, ventilation, pedestrians, and drainage. The control of surrounding rock in the roadway is not only an important factor affecting the economic benefits of mining enterprises, but also related to the life safety of miners. Unlike most underground engineering structures, coal mine roadways are subject to strong mining impacts. Severe mining disturbances often cause the overall uplift, lateral shift, and subsidence of the roadway. At present, the roadway surrounding rock deformation monitoring mainly relies on the arrangement of cross-section measuring stations. The cross-section convergence data ...
