    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

    of inclined shafts materially exceeds that of vertioal shafts. The reason for this may be that the inclined shafts are more often put down in soft rock and pass through faulted zones, whereas, the vertical shafts are usually in the fir.m wall rock.

    Shaft sinking Wikipedia

    Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top

    A shaft may be either vertical or inclined (between 45 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts.
