Bomar is a contracting company operating in both the underground mining and civil engineering industries. Our offices are located in Rivonia, South Africa.
We have over the years established a distinguished record of involvement in some of the major underground projects carried out both within South Africa and elsewhere.
Our approach to projects differs from that of larger, higher profile organisations. Great emphasis is placed on speed and economy, obtained through the application of state-of-the-art technology, and dedicated, focused management.
The company specialises in tunnel development, including decline and raise shafts, both as a contractor (typically in a capacity as a Joint Venture partner with other contracting companies) and as a specialist tendering/cost consulting service provider.
In recent times, the South African hardrock mining industry has recognised the urgent need to introduce mechanisation and new technology into its operations, in order to remain globally competitive. Bomar is, through its accumulated experience and expertise, ideally placed to contribute to this revolutionary change in the production workplace.
Considerable time and effort has been expended by Bomar in IP development, and, as a result, we have developed technology and registered several patents for a number of mechanised mining solutions, which offer real economic benefits to the mining industry. In addition, the technology offers improved workplace safety and significant skills development opportunities to people from historically disadvantaged communities: both of these represent high priority goals for the industry
During 2001, a small diameter TBM (tunnel boring machine) trial at Anglo Platinum’s BRPM Mine, successfully demonstrated the potential for mechanised development of reef raises. Analysis of this performance has led to the design of a machine which is custom built to address the various technical issues unique to a raise environment.
The raise TBM has been developed in conjunction with various other innovations to permit complete mechanisation of stoping operations to take place, centred around the Megamole stoping machine. Detailed presentations are currently ongoing with various Mining House clients regarding the implementation of full scale trials of this machine.
The Directors of Bomar are convinced that Bomar’s technology represents a real opportunity to achieve commercially viable mechanized production within a narrow tabular reef environment, well ahead of other technology-driven competitors
EXPERTISE
As Bomar’ s Managing Director, Mario Pietromartire has 40 years experience in the underground construction industry (30 years of which were gained in the contracting environment).
Mario has achieved and still holds several records in South Africa, namely:
| Drill and blast : |
393m per month in a 30m2 cross section tunnel with a best day advance of 20m. |
| |
189m per month in a 20m2 cross section at 14.5 degrees decline. |
| |
159m per month or 10 812m3 in a 68m2 cross section tunnel. |
| |
7m per day advance per day using the Alimak climber. |
Director, Romano Pietromartire has 25 years experience in tendering and planning in underground construction. He has co-operated with several of the large South African companies in the preparation of tenders and has a reputation throughout the industry as an excellent estimator. He has contributed technically to the development of the various patents.
General Manager, Mark Tursini has more than 20 years extensive experience in most aspects of the mining industry. He has worked on several large projects, the latest being the Gautrain Tunnel, where he was appointed as Contracts Manager. This includes Trackless mining, declines, stoping, mass mining, shaft sinking, civil work, soft soil mining where the technique of Canopy tubes is used. Also in water tunnels where post and pre grouting is done.
His portfolio encompasses the procurement and implementation of New Business as well as the managing of all our mining and construction related activities.
The company’s policy to outsource its professional and specialist resource requirements lends to its low overhead demands.
