Introduction to Cut and Fill Stopping Method

The cut and fill stopping method is a specialized approach within underground mining. It involves the excavation of mineral-rich ore from an underground deposit in a series of steps, followed by backfilling the void with waste material. This method finds its application in deposits with varying ore thicknesses and complexities.

Principles of Cut and Fill Mining

  1. Excavation: The initial step involves creating a horizontal tunnel, or drift, within the ore deposit. This drift is extended vertically as ore extraction progresses.
  2. Ore Removal: Ore is then removed from the drift’s face in horizontal slices. This process leaves a series of open stopes, creating voids in the ore deposit.
  3. Backfilling: To ensure structural stability, the open stopes are backfilled with waste material, such as rock or tailings from processing.
  4. Support Installation: Roof support, such as rock bolts or mesh, is installed to maintain the integrity of the remaining ore and waste material.

Machinery Utilized in Cut and Fill Mining


Jumbo drills are used to create boreholes for explosives in the ore face. These drills are vital for creating space for subsequent ore removal.

LHDs (Load-Haul-Dump Vehicles)

LHDs are used to load ore onto haulage vehicles after it’s been extracted. They also transport waste material for backfilling.

Roof Bolters

Roof bolters are crucial for installing support systems like rock bolts or mesh to ensure the stability of the surrounding rock.

Resources Extracted through Cut and Fill Mining

Ore Deposits

Cut and fill mining is often employed for the extraction of various ore deposits, including gold, silver, lead, zinc, and copper. It’s suitable for deposits with irregular shapes or varying ore grades.

Valuable Minerals

This method can be used to extract valuable minerals like fluorspar, barite, and certain gemstones found in underground deposits.

Advantages and Challenges


  • Effective for irregular ore deposits.
  • Provides good control over ore extraction.
  • Minimizes waste and maximizes ore recovery.


  • Labor-intensive due to its intricate nature.
  • Requires careful planning to prevent stability issues.
  • Can be less efficient for uniform ore deposits.

The cut and fill stopping method serves as an important tool in underground mining, enabling the extraction of valuable resources while maintaining structural integrity. Through a combination of precise excavation, backfilling, and support installation, this method extracts ores and minerals that contribute to industries and economies worldwide. While presenting challenges, the cut and fill stopping method exemplifies the innovation and engineering prowess harnessed to access Earth’s hidden riches.
