Shape Selector 1.15.2-1.14.4 is a really great addon for Ore Excavation, with which you can create your own different matrices to destroy blocks in a certain place with the specified size to maximize the speed of giving spaces the shapes you need.
Using matrices is also useful to avoid hitting some blocks, buildings , or other mechanisms in the selected locations. The mechanism for destroying blocks also has features to destroy blocks along the specified route and so continue layer by layer.
