First photograph above exploration drilling rig. The next photograph is of a underground view of a opal claim that has been heavily worked by opal miners, and as most of the opal level has been removed the opal claim must be made safe and the theory used mostly in modern times as well as in previous times are still the same. The main species of timber used for propping is the Australian cypress pine as there is plentiful amount of this timber available to the miners.
