Iran 5th Country to Achieve Technology of Monitoring Mine Walls with Radar Equipment
“The Information Technology Development Center, with the support of knowledge-based companies, has implemented the project of monitoring mine walls by using radar and technological methods for the first time in the country, and has placed Iran among the top 5 countries in the world (possessing the technology),” Moqimi said.
He described the benefits of this measure as increasing productivity, preventing the collapse of mine walls, and identifying accident-prone areas.
“This technological product has been used as a pilot in the Angouran lead and zinc mine,” Moqimi noted.
Determining slope stability in a mining operation is an important task. This is especially true when the mine workings are close to a potentially unstable slope. A common technique to determine slope stability is to monitor the small precursory movements, which occur prior to collapse. The “slope stability radar” has been developed to remotely scan a rock slope to continuously monitor the spatial deformation of the face.
Using differential radar interferometry, the system can detect deformation movements of a rough wall with sub-millimeter accuracy, and with high spatial and temporal resolution. The effects of atmospheric variations and spurious signals can be reduced via signal processing means.
The advantage of radar over other monitoring techniques is that it provides full area coverage without the need for mounted reflectors or equipment on the wall. In addition, the radar waves adequately penetrate through rain, dust and smoke to give reliable measurements, twenty-four hours a day.
