After the fracture of the central column displacement and tilt. The fracture of the site shown in Figure 1. Because I choose no cobalt plant spare concentrator system. If you want to re-use of concrete pouring a new center column, the demolition of the equipment, installation, coupled with watering concrete health, is expected to be discontinued for 3 months. In order to shorten the shutdown time and reduce the cost of repairs, we do not disassemble the premise, the use of consolidation methods, only
