This report documents a study with the objective to design and develop methods and techniques to reduce longwall equipment move time by 30 percent. A literature study was performed and general foreign and US longwall move practices were documented. Subsequently, four US longwall moves were studied using existing records and on-site time and method studies. These moves were analyzed to identify the positive and negative aspects with respect to time, manpower use, cost and safety. Recommendations are made for each of the four moves studied and a cost benefit analysis is performed to determine the economic feasibility of the recommendations. The actual results are compared with projected results determined by a Critical Path Model analysis of a move incorporating the recommendations. General recommendations are made for improving face-to-face move performance.
