Detecting and masking transient failures in computers used for coal mining operations

The effect of lightning poses a significant problem to computer systems and electronic equipment used in surface and underground mines. Conventional protection schemes such as shielding, insulation, and filtering circuits are not adequate. The field-induced voltages and currents cause transients that can create an upset in digital or computer systems. Two effective approaches are proposed to detect and recover from transient faults when monitoring, processing, or controlling critical mining operations
