A Step-by-Step Procedure for Tests and Assessment of the Automatic Operation of a Powered Roof Support

A powered longwall mining system comprises three basic machines: a shearer, scraper (longwall) conveyor, and roof support. The support as component of complex has two functions. It protects the working from rocks that fall to area where machines people work transports devices in operation proceeds further into seam by means hydraulic actuators are adequately connected controlled or electro-hydraulic system. tests analyses presented developed procedure oriented towards possibility introducing automatic control, without participation an operator. This is important for exploitation seams deposited at great depths. primary objective was develop comprehensive methodology testing evaluating using under operating conditions. conclusions based on analysis valuable source information designers terms increasing efficiency improving occupational safety. authors have proposed evaluation introduce control combines four areas. Tests were carried out order determine extent which could be potentially used future. solution includes certification executive documentation.
