Edge protection: bund height markers
Hanson Aggregates > Baston Fen Quarry, Nr Peterborough > 01778 348546
At Baston Fen Quarry in Market Deeping, the problem of maintaining and checking safety bund heights
has been overcome with some simple physical markers.
The minimum height markers, made by placing a tube in a 45-gallon drum and backfilling with rejected
asphalt, are placed at regular intervals along the bund.
This is particularly important at Baston Fen, where lagoons exist on either side of a haul road. Should the
bund level drop too low, the lagoons are in danger of flooding, potentially causing a road accident.
Gritstone filler disposal
CEMEX UK > Gilfach Quarry, West Glamorgan > 01639 643751
Gilfach Quarry’s coating plant produces significant
amounts of extracted fine filler dust, which is not
economically viable for re-use as a saleable product and is,
therefore, stockpiled for long periods for future restoration.
The need to manage the tip and carry out geo-technical
assessments, combined with restrictions on operating
space and the problem of wind-borne dust, meant that the
only sensible answer was to dispose of the product.
CEMEX has found a solution that is not only
environmentally sound, but also has major safety benefits.
The dust is used to create bunds at the foot of old quarry
faces. This area becomes prohibited and is designed to
catch and retain any rock fall. By moving the stockpile to a more sheltered location, wind-entrained dust
has also been dramatically reduced.
