摘要：
Described the development of an Intrinsically Safe System for continuousmonitoring of load and convergence of powered roof supports installed at longwall faces.The system developed for monitoring of behavior of a powered support in a mechanizedlongwall sublevel caving face.The logging system can be programmed for logging thedata from the sensors at different logging intervals ranging from 16 h to 1 ms for loggingvariation in hydraulic pressures in legs and convergence of the support during progressiveface advance.For recording dynamic loads, the data logger can be programmed to startfast logging, say at 10 ms intervals, when the pressure in a leg reaches a pre-specifiedthreshold value, and continue fast logging until the pressure drops below this thresholdvalue.This fast logging automatically stops when the pressure drops below this thresholdvalue.
