In August, the French and Germans had been working at a depth of 12 metres (39 ft); the size of their charges had reached 3,000 kilograms (6,600 lb). The underground war continued with offensive mining to destroy the opponents' strong points and defensive mining to destroy tunnels, which were 9.1–36.6 metres (30–120 ft) long.

As in siege warfare, tunnel warfare was possible due to the static nature of the fighting.

The eastern Democratic Republic of the Congo (DRC) has a history of conflict, where various armies, rebel groups, and outside actors have profited from mining while contributing to violence and exploitation during wars in the region.
Metallurgists throughout medieval Europe were generally free to move within different regions. For instance, German metallurgists in search of rich precious metal ores took the lead in mining and influenced the course of metal production, not only in East and South Germany but also in almost all of Central Europe and the Eastern Alps.
