| titleOfInvention | Method and device for online monitoring stress and deformation of surrounding rock of roadway |
| abstract | The invention discloses a method and a device for on-line monitoring of roadway surrounding rock stress and deformation, belongs to the technical field of underground coal mine roadway surrounding rock control, and solves the problem that the stress and deformation state of the roadway surrounding rock cannot be reflected intuitively and effectively in real time in the prior art. The method comprises the following steps: step 1, supporting roadway surrounding rock by using a monitoring anchor rod, wherein the monitoring anchor rod comprises an anchor rod body and an anchor rod tray, and the anchor rod tray displays different colors under different deformations; step 2, installing a color capture sensor and a signal transmission device; step 3, changing the stress state and the deformation elongation of the anchor rod tray when the surrounding rock of the roadway deforms, and changing the color reflected by the anchor rod tray under the illumination of lamplight; step 4, monitoring the color of the anchor rod tray in real time by a color capture sensor; step 5, the processor processes the color signal and sends the processed color signal to the display terminal; and 6, taking safety measures according to the deformation condition of the anchor rod tray. The invention can monitor the deformation condition of the surrounding rock of the roadway in real time without the influence of human factors. |
