HWE Mining has won the highest accolade at this year’s Safety & Health Innovation Awards for developing a new, safe way of removing a worn down saver sub from the spindle when drill rods are attached or removed.
The outcome of their endeavours was the insertion of a compression ring that takes on the load from the tightening of the threads, and can be burned out instantly to relieve the connection.
This modification provides a positive coupling and a safe, low energy decoupling of the drill string components. With safety, the new method avoids heavy lifting, working in a congested area, having to contend with excessive potential energy, hydraulic power and impact forces.
As a gesture of confidence all slap spanners, the 15kg tool originally used to do the job, have all been destroyed.
