There are no such bench height requirements and the HSE will definitely not be sending their inspectors around measuring the benches
With these methods, there are often significant deviations --such as the burden, spacing, bench height, subdrilling and hole azimuth and inclination--between the planned and actual geometric parameters of a blast This brings about a variation of the explosive energy, resulting in course fragmentation, inconsistent muck-pile uniformity and higher production costs.
Bench height for mining is planned at three metres which allows for appropriate controls of dilution at ore boundaries.

These carts could be adjusted to exactly bench height, they are extremely stable, and are quite compact.
Block size was based on a quarter of the 20-metre sample spacing between drill sections and a potential 5-metre selective mining unit bench height.
In the blast cycle, volume is typically measured by multiplying the drill pattern used by the average bench height by the number of holes.
