The model of the coal terminal as a system is considered and the physical and management-informational communications between the terminal subsystems are shown in the paper. The model analysis have showed that the probability of failure of such elements as the grab and conveyor belt, would cause the termination of the coal terminal operation and affect the environmental and industrial safety, as well as the coal terminal capacity. The solution of problems on the safe production of works is solved by developing the working technological cards and identifying the regularities of emergency situations occurrence. Each emergency situation is assessed and its impact on the overall safety of the coal terminal is identified. Forecasting and modeling of probable emergencies allows us to determine the ways of their solution. The second important aspect of the coal terminal operation is the technical condition of the grab and conveyor belt and their influence on the environment and capacity reduction. Safe operation depends on the quality of repair work, the availability of the technical documentation and the diagnostic tools, technical measures for the handling equipment maintenance. The handling equipment used at the coal terminal is equipped with both rope and hydraulic grabs. The wear of the grab jaws, or hydraulic cylinders, providing opening/closing of the jaws, leads to loose closure of the grab and consequently the spillages formation. The complexity of the defects timely detection lies in the fact that these elements of the handling equipment are difficult to diagnose, in contrast to the rest of the mechanical equipment. The diagnostic tools considered in the literature allow us to identify the longitudinal breaks of the conveyor belt, the transverse breaks are diagnosed, but the obtained data have a low probability.
