QUARRIES

By

Class 9

Greatstone School

slide2

What is a quarry?

A quarry is a place where materials are taken from the ground to be used by humans.

Normally the material is excavated from the ground. Different materials are used and they can be changed.

slide3

Quarries are very dangerous places.

Do Not Enter

DANGER

You must ask permission to visit a quarry and you will need a guide.

slide4

The material that is taken from a quarry is called aggregate. It is used for all sorts of things.

slide5

The aggregate can be broken down into different sizes. This means it can be used for lots of things.

slide6

Bretts

Lydd Quarry

slide7

Bretts Quarry at Lydd

This quarry collects aggregate and changes it to be used for many different things.

Safety is the most important thing.

The quarry employs lots of local people.

They care for the environment and make sure that the land is left as a natural habitat.

slide8

Health and Safety

All visitors must report to the office. You must not trespass.

Everyone wears a hard hat, a high visibility jacket and suitable footwear.

Safety notices are everywhere to keep you safe.

Machinery has safety stop equipment.

Lorries and moving equipment have warning sounds.

Staff carry walky-talkies.

slide10

It starts when they check what is under the surface by digging down bore holes.

Then they know what is under the surface.

Then they get Glen to come and check the area. Glen is an archaeologist.

Then the aggregate is dug out with big excavators.

slide13

At the main site the aggregate is sorted. Then it can be crushed into smaller sizes ready to be collected. It is kept in piles of different sizes.

slide16

Bretts make sure that the quarry is returned to a natural habitat for wildlife once they have finished with each area.

slide18

We would like to thank the people at Groundwork for making it possible and especially Jenny Glanfield who helped for five weeks.

We also thank the National Lottery for donating money to cover the costs.

A huge thank you goes to everyone at Bretts Quarry, Lydd.

We would also like to thank all the adults who helped us on our trip.
