The hanging wall of an inclined shaft is, of course, more difficult to support in weak ground than the walls of a vertical shaft. Where vein material is soft and apt to cave. J. and the walls are strong, inclined shafts are usually put down in the footwall side on the vein. Shafts so placed have the advantage over vertical shafts of being

Drifts/Inclined Shafts Introduction underground COAL

Drifts/Inclined Shafts. The angle at which a drift becomes an inclined shaft is somewhat subjective, but there is some agreement that anything above 30 o to the horizontal is a shaft, not a drift.. A major advantage of drift or inclined shaft access versus vertical shaft access is the ability to move large volumes of equipment, materials and personnel in a properly designed and equipped drift ...
