University Of Kentucky Mine Ventilation Manager

The University of Kentucky Mine Ventilation Manager (UKMVM) is a system that contains Level Five knowledge bases and comprises an expert mine ventilation management system. The package uses production rule language (PRL) to interpret data monitored from sensors, e.g., for airflow, temperature, and concentration of gases, in an underground mining environment. Activated from the PRL knowledge bases are Pascal subprograms which (1) organize the monitored data to set up emergency consultations, (2) display graphic representations of a mine's ventilation network with the latest sensor readings, (3) provide interactive updating of mine ventilation parameters, e.g., resistance changes, revised flow requirements, and new regulator and fan settings. Also activated from these knowledge bases are programs which (1) monitor airflow, temperature and gas concentrations from a physical mine ventilation model and (2) adjust regulator openings and fan rpm's. Thus, as an expert system the UKMVM not only presents advisory consultations for underground environmental emergencies, but also serves as an interface between the monitoring and responsive control aspects in the continuous maintenance of normal mine ventilation.
