Mine timber carried the load, while ceramic breaks separated each shoe from the next.

Ferra checked the arrangement twice before permitting the next descent.
She inspected each section before another frame followed it down.
Withdrawal lines returned to Loccy's surface wheel, so one failed support could not take the complete route.
"If one section shifts, pull only that section," Ferra told Loccy while she marked the line with white chalk. "The mine must never receive a single correction through all of them."
The final frame settled against the lowest wall without completing a continuous face.
Ferra struck each joint, then marked the route safe on Hans's sheet.
