| Abstract | An iterative method employing simulation technique was developed for
optimization of the selection of equipment for hard rock full face drill and blast
method of tunnelling. Specifications of equipment available in different categories
were obtained through correspondence with the manufacturers. This information
was stored with standardized formats in several databases. Formats were
standardized based on their relevance in depicting equipment characteristics and
requirements of the simulation program. A preliminary equipment selection
program was developed to generate filtering conditions to access equipment
databases. This program indicates dimensional ranges for equipment options
fitting a particular tunnel size and method of operations adopted. Options
generated by databases can be applied to the simulation program which provides
total cycle time and individual activity times for a given tunnel segment. This
program generates times for individual operations through random accession of
appropriate probability distributions. Simulation is carried out with these
generated time values. Statistical analysis of the total cycle time indicates the level
of confidence with which it will lie within a specified time interval, which is kept
as an indicator to optimize the selection of equipment. By changing equipment
methods and advance per round iterations are used to arrive at the optimum
tunnelling advance rate compatible with the system layout. |
