Our quarry clients regularly contract Landair Surveys to fly aerial imagery of their quarry sites throughout Australia twice a year to measure Stockpile Volumes.
Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. The materials produced by quarrying are essential to our everyday lives, providing the construction materials to build roads and buildings as well as many other industrial and agricultural uses.
Once the materials are extracted from the ground, they are processed using crushers and screens and stored in stockpiles awaiting transport. Photogrammetry can be a very important tool in measuring the volume of the Stockpiles. These volumes are used to calculate the amount of resources a quarry has.
Below is an image of the stockpiles on a quarry floor and stockpiles over a quarry bench. This image shows 1 metre contours over the stockpiles.
