Underground quarries are voids dug to exploit mineral resources mainly for construction, unlike mines used for carboniferous or metallic materials. These sites extract sedimentary rocks that result from the accumulation of solid sediments or clasts deposited in superimposed layers called strata.

Photographs present the techniques used to consolidate subterranean spaces, such as masonry pillars, turned pillars, or concrete injections. They also reveal the transport systems used for stone blocks, from narrow tracks along haulage axes to historic river access and horse-drawn wooden carts.

The following themes cover the extraction, consolidation, and transport methods used in underground quarries.
