This system is designed to prevent the occurrence of any unsafe combination of events in the monitoring and control of booster fans in underground coal mines. Although improved ventilation efficiencies and reduced leakage may result from using these fans, the potential for uncontrolled recirculation still exists. Because of this, the U.S. Mine Safety and Health Adminstration does not currently allow coal mine operators to use booster fans. However, with the advent of reliable mine monitoring systems, these fans can be operated safely. It is the intent of this study to provide coal mine operators with dependable fan control software, i.e., a system that is sufficiently flexible to handle the output of many transducers and perform simultaneously important tasks such as data evaluation and process control. The process control is carried out by means of an expert system supported by a knowledge data base. If an abnormal condition in the mine is detected, the program will check the mine-monitoring system for defective units and faults in the data transmission network. Only noise-free information will be used to undertake a corrective action.
