This paper deals with the evolution of present mechanised declining and orebody development practices at Kambalda, since their inception in 1969. Eight separate decline accesses have been established over the past eighteen years and to date some 175 kilometres of declining and lateral development has been achieved utilizing a wide range of mechanised development and mucking units. Improvements in-the range of equipment available, functionalization of the develop- ment tasks and the resultant changes to piecework contract structuring have all contributed to the improved performances achieved in this concept of mine development. Even though numerous development advance rate records have been established at Kambalda, an ongoing evaluation of changes to both drilling and mucking units is underway to further improve these development performance rates.
