A coal mine roadway deformation monitoring device and its application method

Abstract

The invention relates to a coal mine tunnel deformation monitoring device and a using method thereof, and belongs to the field of coal mine safety monitoring. The monitoring device comprises an installation platform, a sensor and execution mechanism and an ARM processor. The device is connected to a mine car via the installation platform, and reaches a corresponding measuring point under tractionof an electric locomotive to monitor the tunnel section; a range finding device is leveled automatically via a sensing technology, and the accuracy of subsequent measurement is ensured; the tunnel deformation is monitored accurately via a laser range finding technology; and a high-definition camera is used to carry out snapshot on the abnormal tunnel obtained by monitoring, and basis is provided for subsequent tunnel maintenance. The device is provided with an explosion-proof housing, is reasonable and reliable in structural design, is high in efficiency and low in error, the labor intensity of coal mine workers is reduced effectively, and the automatic degree of the mine is improved.

Description

technical field [0001] The invention discloses a coal mine roadway deformation monitoring device and an application method thereof, which is particularly suitable for rapid and automatic monitoring of coal mine roadway deformation and belongs to the field of coal mine safety monitoring. Background technique [0002] With the depletion of shallow coal resources in my country and the increasing depth of mine mining, the physical and mechanical properties of the roadway surrounding rock under the action of high in-situ stress in the deep part are very different from those in the shallow part, especially with the characteristics of large deformation. The roadway deformation and collapse accidents caused by the mining of deep surrounding rocks are more and more serious, seriously affecting the normal production of mines and posing a threat to the personal safety of workers. [0003] At present, there are two methods for monitoring the deformation of coal mine roadways: one is man...
