The planning phase of a new workplace, such as a mining extension or new mine, must incorporate the radiation safety aspect, and the design will optimise production and safety aspects. In this regard, a pre-operational estimate of expected radon and external radiation levels has high value. One example is the routing and quantification of ventilation paths to maintain radon at acceptable levels.
PARC Scientific has developed mathematical models to estimate radon levels in any mining environment, accounting for uranium content, workplace geometry and air movement and quantity. The model was validated in two South African underground mines, and has been used for mine planning in a number of mine developments. Modelling furthermore allows optimisation of ventilation and geometries in existing mines as well as trouble shooting where high values occur.
