Excavation Methods Vertical Shafts underground COAL

Excavation Methods. Vertical Shafts. There are 4 methods in general use: Conventional drill, blast & remove stone ("muck out") to surface with a winder.If the shaft is to be "lined" (i.e. sides to be covered with a concrete or even a steel lining), this is normally placed as the shaft is excavated.

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

Handbook to best practices for mine shafts protection

Collapse is characterised by rapid movement caused by gravity which is vertical and may be significant. It can cause major consequences for the risk factors: the damage, even the demolition of infrastructure or buildings, physical injury or loss of human life. Collapses induced by the presence of mine shaft can occur according to different
