Based on the maps and archaeological evidence, it appears that the narrow, southern trench was the actual palisade wall as shown on Labastida, and the northern trench was a narrow excavation probably made to supply the earth for a banquette, or firing step, against the northern face of the palisade, and to be a space where the defenders could step down to get their heads below the firing slots left in the palisade wall...

Record 5 1999-05-11

English

Subject field(s)
  • Mining Operations
CONT

The driving of a narrow roadway results in the development of a pressure arch over the excavation. The strata within the arch bend slightly and cease to support the overlying beds, and the load is transferred to the solid coal or rock along the sides. The wider the roadway, the greater is the span of the arch and its height at the crown. A similar but larger pressure arch is formed across a longwall face, with one leg resting on the solid coal and the other on the solid pack behind the coal face.

PHR

Roadway pressure arch, roof pressure arch, span of pressure arch, width of pressure arch.
