The open-pit extraction of stone and other minerals, crushed into aggregate for concrete and road base.

## What is Quarrying?

Quarrying is the extraction of raw construction materials, such as stone, from the earth's surface. Unlike deep-shaft mining for coal or gold, a quarry is generally an open pit. Drilling and controlled blasting break the bedrock into chunks, and crushers then reduce them to the aggregate sizes needed for concrete or road base.

## Practical example

A highway project needs 5 million tons of gravel for the road sub-base. The contractor leases a rocky hill nearby and sets up a captive quarry. The crew blasts the rock face daily and passes the boulders through jaw crushers to make the 40 mm and 20 mm aggregates the highway needs.

## In SuperWise

Aggregate from a quarry is a material resource in SuperWise, bought on a purchase order. Each truck that arrives is recorded as a [material delivery challan](https://superwise.site/glossary/material-delivery-challan/) against the PO line, with the supplier's challan number, vehicle registration, driver, quantity and photos. Deliveries cannot take the total past the maximum quantity on the PO line.
