Get Price· Underground Coal Mining There are 5 types/ways of underground coal mining 1 Drift Mining Drift Mining is possible where the coal seam intersects the surface The mine enters the seam in a horizontal direction following the coal A drift may or may not intersect the ground surface This kind of mining is done when the rock or mineral is on
Get PriceDrifts/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 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
Get PriceThis gives a more continuous process and should give a good drift profile The use is limited by the grades involved maximum 1 4 and the hardness of the material to be cut maximum 60 80 MPa UCS Use of a tunnel boring machine Provides a good circular profile which is good for stability and ventilation but usually requires a false floor to
