An intrinsically safe, continuous dust control parameter monitoring system was assembled and the capabilities of the system to augment a coal mine dust control plan was demonstrated. The system consists of a data acquisition system, data storage modules, sensors, solid state relays, safety barriers, and battery power supplies. It was designed so that it could be adapted to either a continuous miner or a longwall shearer with minimum modification to the existing machine. The parameters selected for monitoring were air velocity, water supply pressures, water flow quantity, machine vibration, shearer tram rate for the longwall shearer, mining machine hydraulic supply pressure, and for the continuous miner, pressure drop of the dust scrubber system. In mine studies showed that the monitoring system is a viable instrument for continuously observing and recording dust control parameter activities in underground mining and that the system can be used as a tool for keeping respirable dust levels at a minimum.
