Mining Timbers: The Backbone of Shaft Safety

Historical Use of Timbers in Western Mines

For more than a century, mining in the American West has depended on timber cribbing and support structures to keep shafts stable. Early miners quickly learned that timber-lined tunnels were essential for preventing cave-ins, supporting heavy loads, and protecting crews working deep underground.

Even today, in an industry shaped by new technology, timber remains an irreplaceable material for underground operations. Its strength, availability, and adaptability make it the preferred choice for reinforcing shafts across Utah, Colorado, Wyoming, Idaho, Arizona, and Montana.

Types of Mining Timbers (Caps, Wedges, Custom Sizes)

At Dark Horse Timber, we provide a range of specialized mining timbers designed for underground safety and load-bearing applications:

  • Caps – Heavy timbers placed horizontally to distribute weight and stabilize cribbing structures.

  • Wedges – Cut to lock timbers in place, securing underground supports and preventing movement under stress.

  • Cribbing Timbers – Stacked to form sturdy retaining walls or column-like supports inside shafts.

  • Custom Sizes – Milled to exact specifications, whether for oversized beams, shorter blocking cuts, or project-specific requirements.

Our mining lumber is cut rough for maximum strength and durability, ensuring it stands up to the toughest underground conditions.

Why Strength and Custom Cuts Matter

In underground environments, there is no room for error. Weak or improperly sized timbers can result in:

  • Shaft collapse

  • Unsafe working conditions

  • Delays and costly downtime

That’s why contractors and mine operators turn to rough cut, full-dimension timbers. A true 8x8 beam from Dark Horse Timber provides more load capacity than a planed, dimensional cut. When every inch of strength counts, our custom milling ensures the right fit for every application.
