Rock bolts are used to tie unstable or potentially unstable rock structures into the slope. There are static and tensioned rock bolts:
The logic behind a static bolt is that if the structure is safe enough to drill into and install rock bolts, it already has an inherent factor of safety. If the stability of the structure is adversely affected in the future the static bolt will automatically go into tension with the exact amount of force and in the exact location that it should.
Deepwell Corporation was incorporated in 1972 after acquiring all Plants, Equipment and stores of the U.S. Firm M/s Harold T.Smith which winded up its drilling business in Pakistan. Since its inception Deepwell has been continuously updating and replenishing its equipment and services to meet the modern demands of the industry through Research and Development.
