Drilling machines can bore access holes directly using very large rotating drill heads
Open-pit mining uses large holes in the ground that are excavated to the depth of the desired product.
Strip mining is similar to open-pit, but typically the desired ore is closer to the surface.

Sand mining is used to extract both sand for construction uses, and to mine minerals.
