The invention further discloses a monitoring method by using the device of monitoring the fissure deep fracture development and forecasting the dangerous rock body collapse by using the geological radar. The device of monitoring the fissure deep fracture development and forecasting the dangerous rock body collapse by using the geological radar and the monitoring method make use of contactless and long-distance detection features of the geological radar, efficiently achieve monitoring of dangerous rock body fissure deep fracture development, then achieve collapse forecasting of a dangerous rock body according to developmental situation and change features of the dangerous rock body and combination of relative judging criteria, and have the advantages of being simple in operation, prone to data record, efficient, accurate and the like.

Description

[0001] Technical field [0002] The invention relates to a rock mass collapse prediction device and method, in particular to a device and a monitoring method for monitoring the development of deep cracks by using geological radar. Background technique [0003] The safety monitoring of dangerous rock masses has a long history, and there are many monitoring methods. The traditional method adopts the intuitive micrometer observation method, which is to directly measure the crack width change of the dangerous rock mass with a micrometer. The measurement method is intuitive and simple. However, there are problems such as poor accuracy and inability to record. With the further development of science and technology, GPS, INSAR 3D laser scanners, etc. have also been introduced into the safety inspection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the monitoring requirements well, and the cost is expensive. In the engineering applic...

[0003] The safety monitoring research of dangerous rock mass has a long history, and there are many monitoring methods. The traditional method adopts the intuitive micrometer observation method, which is to directly measure the crack width change of dangerous rock mass with a micrometer. The measurement method is intuitive and simple. However, there are problems such as poor accuracy and inability to record

With the further development of science and technology, GPS and INSAR three-dimensional laser scanners have also been introduced into the safety detection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the monitoring requirements, and the cost is expensive. In the engineering application, it can not play a very good role in monitoring and predicting the collapse of dangerous rock mass.

Moreover, the above-mentioned methods only reflect the collapse trend of dangerous rock masses by detecting the displacement changes of the upper part of the cracks, etc., and do not propose any scientific monitoring means for the development of deep cracks in the cracks that directly cause the collapse of dangerous rock masses.
