Abstract
Provided are a long-term monitoring apparatus and method for surrounding rock fracture evolution process triggered by multiple-source dynamic disturbances. The apparatus includes a machine body framework, a borehole wall surrounding rock image acquisition module, a borehole wall multiple-source vibration monitoring module, an in-borehole walking module, and a monitoring signal storage and transmission module. The borehole wall surrounding rock image acquisition module, the borehole wall multiple-source vibration monitoring module, the in-borehole walking module, and the monitoring signal storage and transmission module are sequentially arranged on the machine body framework from front to back. The monitoring signal storage and transmission module is connected in a communicative manner to a computer outside a borehole. The present invention can achieve integrated monitoring of imaging and vibration within a borehole. Also, the present invention can achieve long-term continuous monitoring of the fracture evolution process of surrounding rock in risk regions.
