The article focuses on the specifics of the development and implementation of a dual system consisting of a subsystem for designing production units' power supply and a subsystem of assessing knowledge of coal mine electrical services employees. The paper identifies quantitative and qualitative changes of recent years at the companies engaged in underground coal mining. Furthermore, the paper provides a rationale for the dual system and describes an algorithm for generation of a single database, which includes calculation subsystem database, subsystem database for knowledge assessment and a virtual simulator for assessing staff readiness to work with coalmines producing areas power supply. We consider testing algorithms (knowledge control), further training and authorization of coalmine electrical services personnel for maintenance, calculations, mounting, dismantling and adjustment of power supply systems of coalmine producing units. Moreover, we propose dual system's operating procedures and consider a beneficial impact due to introduction of the dual system.
