History
Rockma started operations in 1999 and has since sold hundreds of systems to the mining industry, both surface and underground mining, tunneling projects, geotechnical surveys, diamond drilling, quarry etc. We specialize in the interpretation of rock properties, but the products have evolved over the years, offering comprehensive solutions for various production applications.
For large open pit, we have a complete drill management system that includes everything from planning with advanced systems for establishing drilling plans, high precision GPS navigation and positioning, avoidance of drilling into old drill pipes, systems to obtain drilling depth for flat soles, explosive properties, consumption of materials, advanced monitoring , production statistics, on-line monitoring of all drilling activities, etc. Our open pit clients include one of the world’s biggest open pit, Sishen Iron Ore Mine in South Africa. Currently, Anglo American is ROCKMA’s largest customer in South Africa.
In Scandinavia, we have sold many systems for tunnel operation. One of the most modern systems today is National Rail subway system in Larvik, Norway. A large number of drilling rigs are connected so that each completed hole drilled directly available to all users. A unique overview of the business in real time with rock properties is presented graphically. Our largest customers in Scandinavia is the Swedish Transport Administration, Public Roads Administration in Norway and the Norwegian National Rail Administration.
Rockma also has a unique system for diamond drilling.
Technology
Rockmas technology enables highly accurate and precise information about the rock mass.
The drilling process and rock interpretation can be displayed in real time to the operator and sent with modern technology to users of Rockma Software.
The rock properties we calculate/present are normally:
◾ The rock compressive strength ( UCS ) presented in MPa
◾ Fractures, presented as fracture frequency (%) or RQD
◾ Water conditions of the rock mass
◾ Blasting properties
◾ Grouting / classes
◾ Rock support
◾ Ore / waste
◾ Also other properties can be calibrated against if reference data are available

Drilling process raw data, that we use as a basis for our calculations is often called:
◾ MWD (Measurement While Drilling)
◾ Drill monitoring
◾ Also other names occurs for the process of collecting drill data

Many types of drill rigs are equipped with a system for the collection of data, in those cases , we use that data. If the drill rig doesn’t have this pre-installed then we have a complete system for this.
We also supply high – precision GPS and complete management systems.
Digital mapping
The name or concept ”Digital Mapping” comes from analyzing and presenting drill monitoring data. Drill monitoring can also be called MWD (Measurement While Drilling). Drill monitoring or MWD is different names for registration of drill parameters during rock drilling
ROCKMA is a company that develops methods for analyzing these parameters and also develops software for graphical presentation of the rock mass. The graphical presentation is generated automatically and it is very user friendly. All handling is digital. This is why the method is called ”Digital Mapping”.
ROCKMA can be used for all drilling methods, all brands and models. Many drill rigs can be delivered with MWD-systems (drill monitoring systems) often as an option. This is not necessary. ROCKMA has possibility to sell and mount complete logging system on all types of drill rigs. ROCKMA’s hardware (monitoring system) is optimized for the analysis and built on that basis.
The analysis of drill monitoring data has been developed to generate very detail rock mass information. Whole handling in modern systems is easy, all analysis is automatically generated and gives foundation for a quick decision.
To take care of and use information when drilling is performed can give huge economical and safety benefits. In some application just one decision based on this information can give a payback for the whole system cost.
