n this study, haif-face and full-face mefhods, which are lurn around
meîhods for shearer to starî a new web where doubîe ended drum shearers are used,
were invesîigaled. Time-moSion studies were carried out in the fully mechanized
longwalls where above melhods are employed. Machine 's movements for each method
were expîained wiih equations in detaiL Cycle îimes spent for extracting one ~^'eb of
coal by shearer were convevted inîo equaîions.
