Special Methods of Shaft Sinking - DJ DESHMUKH VOL 1 - THE ULTIMATE OM MS COURSE

In this video, we explore the special methods of shaft sinking used in mining engineering when ordinary methods are not suitable. These techniques are essential for dealing with challenging conditions such as loose or unstable ground, excessively watery strata, or a combination of both.
Key Topics Covered:
1. Piling Method:
- Ideal for sinking through loose deposits like sand, mud, or alluvium.
- Uses interlocking steel piles to form a stable, water-tight ring for excavation.
2. Caisson Method:
- Includes the Open Caisson Method, Forced Drop Shaft Method, and Pneumatic Caisson Method.
- Effective for sinking through tough and loose ground or when dealing with high skin friction.
3. Freezing Method:
- Suitable for unstable or friable strata with heavy water inflow.
- Involves creating a large block of frozen ground to prevent water influx during shaft sinking.
4. Cementation Method:
- Applicable to fissured water-bearing strata, except in running sand or loose ground.
- Involves treating the ground around the shaft to stabilize collapsing ground, reduce water inflow, avoid flooding, and prevent sand boiling.
Each method is designed to address specific geological challenges, ensuring safe and efficient shaft sinking operations. Watch the video to learn more about these advanced techniques and their applications in the mining industry.
