Device for Controlling the Mining Elevator Transportation Process

The article deals with the development, structure, design and control of elevator transportation processes using PLCs and their testing for their application in the automation of such processes, addressing the case of automatic control of an extraction machine was addressed. The main functional and system requirements and specifications for the extraction machine are presented, also describing the design and the simulation of the control algorithm. The coding using the Ladder program and the off-line testing of the system, respectively its on-line testing, are presented. Based on experimentation in laboratory conditions, we tested and demonstrated the capabilities and usefulness of using the command-and-control computer system with PLC for vertical extraction. The practical implications are those stemming from the shift of paradigm, from hardware-oriented to software oriented, thus driving significant cost efficiency through lower installation and maintenance costs, faster installation and great robustness, leading to a reduced total cost of ownership over other solutions.
