Coal mine tunnel surrounding rock deformation monitoring device

Abstract

The invention discloses a coal mine tunnel surrounding rock deformation monitoring device. The device comprises a rail arranged along a tunnel, a monitoring platform, a first driving device, a laser radar, a controller, a wireless communication module, a communication module group and a cell module group, wherein the monitoring platform is provided with a roller and is connected to the rail; the first driving device is connected into the monitoring platform and is connected to the roller, and is used for driving the monitoring platform to move along the rail; the laser radar is arranged on thefront end of the monitoring platform and is used for collecting deformation information in a tunnel; the controller is electrically connected to the laser radar and is used for receiving the deformation information; the wireless communication module is electrically connected to the controller and is used for receiving the deformation information passing through the controller; the communication module group is arranged in the tunnel, is electrically connected to the wireless communication module and is used for receiving the deformation information passing through the wireless communication module and transmitting the deformation information to a ground data center; and the cell module group is electrically connected to the first driving device and the controller. The monitoring device can obtain a surrounding rock deformation condition under mine in real time, measurement is accurate, precision is high, and manpower is saved.

Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to a monitoring device for surrounding rock deformation of a coal mine roadway. Background technique [0002] For a long time, the deformation, instability and failure of surrounding rocks in various types of roadways such as deep, soft rock, and large sections have seriously affected the safety and economic benefits of coal mines and other underground operations. Accidents such as roof falls caused by roadway surrounding rock instability are One of the main sources of coal mine casualties. Deformation monitoring of roadway surrounding rock is an important means for predicting instability and failure of roadway surrounding rock, and evaluating the effectiveness of support methods and parameters. At present, the method of measuring the deformation of the surrounding rock of the roadway in the coal mine is still the manual measurement method such as the cross measurement method, wh...

AI Technical Summary

Problems solved by technology

At present, the method of measuring the deformation of the surrounding rock in the roadway of the coal mine is still the manual measurement method such as the cross measurement method, the measurement accuracy is low, the manpower consumption is large, and the deformation of the surrounding rock in the mine cannot be obtained in real time.
