Abstract:

The mechanization of longwall mining is an inevitable trend in underground coal industry. At present, Vietnam has operated many mechanized longwall faces in Quang Ninh coal field. The mechanised longwall at Seam 11, Centre area Duong Huy coal mine has been operated and its mechanised equipment complex basically performs as designed. However, the actual production shows that the longwall equipment has not reached its maximum capacity while the arrangement of production remains inadequate. Apart from objective factors, the initial production arrangement chart did not consider the maximization of the mechanised complex. In this paper, the authors used field observation and theoretical methods for improvement of production arrangement chart for the mechanised longwall at Seam 11, Duong Huy coal mine. An improved chart of production arrangement (and subsequently a chart of labour arrangement) has been developed based on actual time cost for each production task. According to the new chart, the production can be now implemented with 7 cuts per day - night. This arrangement well corresponds with practical production capacity that increases the longwall productivity.
