Downreaming with a raise boring rig is a drilling method that we have worked out to be able to connect existing levels to already completed shafts or cavities.
We currently have two rigs that are equipped to carry out this drilling in terms of production.
Our downreaming can be done in dimensions between (13 3/4″ to 2.4m in diameter) with a hole length of up to 30M
