摘要

This work presents the development of a prototype SLAM II computer simulation model of underground production mining based upon a specific mining complex found at Inco Limited, Manitoba Division. Mining processes included in the model consist of production drilling and blasting, mucking and hauling, train tramming, and backfilling. Specific work shifts and chimney capacities are fixed at the start of the first simulation run, while activity times, hauling and tramming capacities, and equipment uptimes and downtimes are randomly sampled from their respective distributions.;Logic diagrams and time charts are used as communication tools to present some of the operational characteristics of the model. As a case study, the model was used to determine activity and system bottlenecks, as well as, the expected average daily production rate based on four typical mining blocks found at the complex.;Inputs to the model are easily changed to examine various other mining blocks and types of system configurations. Model outputs include the averages and confidence intervals for various availability ratios, production rates, activity times, as well as, a production schedule table. In addition, similar information is available on a per run basis, along with the daily and cumulative production rates, as well as, preliminary cost information.;The results from the study showed that computer simulation is an excellent tool for evaluating complex systems such as underground production mining.
