Drifts/Inclined Shafts Introduction underground COAL

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/inclined shaft, whilst adopting gradients of 1:8 or less enables rubber tyred equipment to be utilised which significantly improves operational flexibility

MINE DEVELOPMENT – ACCESS TO DEPOSIT

2012-9-6  deposit is one that mine engineers and planners are faced with when investigating the viability of most shallow deposits. Basically there are four approaches to gain access to an orebody; namely, adits, incline shafts, vertical shafts, and declines or ramps. The four methods are briefly discussed in this paper for the sake of continuity, but

necessities. Moreover inclined shafts of a degree of flatness possible for moderate depths become too long to be used economically from the surface. The vast majority of metal-mining shafts fall into the first class, those of moderate depths. Yet, as time goes on and ore-deposits are exhausted to lower planes, problems of depth will become more common.
