Sublevels will be established at 18-m vertical intervals
, with primary cross cuts spaced approximately 200 m apart to access the 16 mineralized veins in the deposit.
The basic espalier form, which mimics the cordon system for cultivation of grapes, simply requires you to fasten horizontal lengths of baling wire at 14-inch vertical intervals
up the wall or fence against which your fruit tree will grow.
X-ray intensity can be adjusted at vertical intervals
to provide g reater strength at the top and bottom of a jar or bottle where the glass is thicker.
Sub levels were initially developed at 20 m intervals, with drawpoints situated within main footwall extraction haulage levels at 80 m vertical intervals
The original access to the ore is via horizontal adits and drifts driven parallel to the strike of the reef at varying vertical intervals
