| titleOfInvention | Method and equipment for predicting rock burst through brittle micro-failure phenomenon of rock mass |
| abstract | The invention discloses a method for predicting rock burst for brittle micro-failure of rock mass, which comprises a current monitoring module, an image contrast monitoring module and a pressure monitoring module, wherein the current monitoring module is used for monitoring the current of rock mass and the image contrast monitoring module; wherein, the current monitoring module is: the probe is deeply inserted into the inner part of the roadway wall, a stable voltage power supply is used for supplying power, and a method for monitoring rock burst by adopting a curve of current change is adopted; the image contrast monitoring module is as follows: shooting fine cracks in the wall of the roadway by using a camera, comparing the fine cracks to obtain a crack change curve, and monitoring rock burst; the method has the advantages that the method converts the damage precursors of the brittle rocks into more intuitive current signals and images with rapid feedback, predicts the crack extension trend and the rock burst generation trend, performs prevention treatment and reduces the loss to be brought. |
