INTRODUCTION. A number of underground mining projects, both in Australia and internationally, are implementing or proposing to implement mass mining methods. These methods include sublevel caving (SLC), block caving (BC) and panel caving (PC). The underlying philosophy is to create an underground ‘rock factory’.

· The average haulage and hoisting costs for these groups ranged from $0.1135 to $0.4025 per ton of ore mined, and the range for 47 individual mines was from $0,086 to $1,848. Elsing has tabulated transportation costs at 66 mines, which show averages by groups ranging from $0,120 per ton mined to $0,556. It is therefore apparent

· "The amount of material moved for excavating a prevoid for the access is quite different for a shaft and a ramp (usually up to ten times for a ramp). As soon as the thickness of the alluvial surface material is too high to be removed with bearable technical efforts, shafts are preferred as the costs for developing a ramp through 100 m and more

· The mining industry faces many difficult challenges, for example, lower ore grades, smaller and deeper deposits, and longer transportation distances. In the past, there have been remarkable innovations in both equipment and the types of mining methods for which it is used, which have resulted in economies of scale. This has led to an increased
