Evaluation of the Kloswall longwall mining system. Final report
This report presents the results of design studies and critical requiremental tests of a new longwall mining system specifically designed to extract a very deep web (48 inches or deeper) from a longwall panel. The report includes a productivity and cost analysis comparing the new mining system with a conventional longwall operation taking a 30-inch wide web. The analysis shows the new system will increase annual production and return on investment in most cases. The report also includes conceptual drawings and specifications for a high capacity three-drum shearer and a unique shield type of roof support specifically designed for very wide web operation. The advantages and problems associated with wide web mining are discussed in general and as they relate specifically to the equipment selected for the new mining system. Details of the critical testing and the test results are presented. The study concludes by recommending that surface tests of the haulage and guidance system be conducted as the follow-on work.
