Abstract :
A database was designed to accumulate the relevant information for all existing high-voltage longwall systems. This information was obtained from the Proposed Decision and Order documents issued by the Mine Safety and Health Administration (MSHA). Additional sources of information were obtained from MSHA approval documents and online diagrams of all active high-voltage longwalls. The data collected from these documents were incorporated into the design of a database that reflects the electrical information from each high-voltage longwall system. An analysis of the electrical database shows a trend towards the use of larger-section power centers, longer trailing power cables, higher-voltage utilization equipment, and larger horsepower motors. This gives mine operators the option of varying the panel length and width to obtain a greater efficiency
