Abstract :
Automation of longwall roof supports can be used as a tool to increase coal mine safety and productivity. To determine the value of this tool, both in terms of safety and productivity, the capabilities of roof support electronic control systems supplied by four manufacturers were reviewed. In addition to the system capabilities, present uses of the systems, system reliability, and an evolution of the electrohydraulic shield are discussed.<>
