Computer Assisted Stope Design

The algorithms to model three stoping methods - sublevel, down- the-hole (DTH) and cut and fill stoping have been developed. These algorithms are capable of designing and performing economic analysis for one or more number of stopes in a continuous orebody. The design and economic analysis of each individual stope are first obtained. This is followed by the composite stope design layout and overall economics of the stopes under study. This paper describes only the stope design aspects of these models. The programs have been written using Fortran 77 with Tektronix graphical aids available at Imperial College Computer Centre (ICCC) London and are based on the basic data obtained from Khetri Copper Complex (KCC) and Rajpura Dariba (a zinc mine) in India. Minor modifications, however, may be necessary in some routines when used on other systems and for other mines.
