DEVELOPMENT OF FLAT & VERTICAL EXCAVATIONS
This involves the excavating of lateral development ends and vertical developments to the required dimensions using both conventional and mechanised methodologies. The designs of the excavations are that of the mine owners and as such are used to baseline the quality control parameters of the works to be undertaken. Bora has undertaken similar works with Palabora Copper Mine and has successfully delivered a high-end quality of works which included the development of Raise Bora Chamber facilities.
UNDERGROUND REHABILITATION SERVICES
This involves the opening-up of the old areas that have converged, or the walls (side, footwall and hanging wall) of the excavations have curved/ or collapsed in due to the excessive pressure build up. Once such excavations are re-opened to the required dimensions, the re-supporting of such excavations with the right support units in line with RME is applied. Current similar works is being executed by Bora in Palabora Copper Mine.
INSTALLATION OF SUPPORT UNITS
This involves the supporting of both side and hanging walls of the excavation or development end to enable it to sustain the distributional pressure to maintain its dimensions during the required operational phase of the mine. All support units as recommended by RME are installed to precession to achieve effective support mechanism of every unit. Similar work has been undertaken in Palabora Copper Mine in both rehabilitation and during the development phase of raisebore facilities.
CONSTRUCTION CIVILS & BATCHING SERVICES
Emergent from Bora’s sister company, which mainly deals with the supply of shotcrete materials, Bora has mastered the art of designing and setting up efficient batching plants to achieve minimal running costs for the process for both shotcrete and concrete batching services. All related civils and other peripheral constructions required to complement the application of shotcrete and concrete is done in house. This includes the underground roadways concrete paving, bullnose cementation, flooring, concrete lining during sets installations and old areas back lining.
VERTICAL & LONG HOLE SOLUTIONS
A niche market to assign Vertical and Long Hole drilling services to external service providers has surfaced and to that effect, Bora is championing a safe and efficient way to achieve best results. Bora uses a remotely controlled drilling machine to safely and accurately develop the Ore passes, Services holes, Vent Raises, Silos, etc. Another cost effective way to get the best results with a man-free box holes.
CONVEYOR BELT INSTALLATION & MAINTENANCE
This involves the supply of the right conveyor belt specified material to be installed, from the construction of conveyor steel frame to the installation of the belt. Maintenance of the belt to ensure continuous availability of which minimising downtimes is assigned to specialists within Bora. A regular pro-active maintenance schedule is drawn to ensure that its implementation has a minimum or no negative impact to the daily progress of the production activities.
