A Study of critical path for feasibility studies of mining projects

This work develops a model for design and realisation of prefeasibility and feasibility studies of a mining project. The model provides the structure of various necessary procedures to establish the feasibility studies and presents a logical system of task sequencing and information circulating between tasks. The specifications of mining projects, particularly their duration, complexity and high costs, necessitate design and realisation of feasibility study based on the sufficient understanding of task behaviour and the critical path method view. For this purpose, critical paths with the highest frequency of occurrence were studied through several simulations. In addition, the critical tasks and subtasks with the most probability were identified. The model introduced in this paper can serve as a perfect tool in feasibility study of a mining project. It can also be used as a basis of future development of mining software.
