Trong bài viết này, nhóm tác giả đã sử dụng phương pháp phân tích lý thuyết kết hợp quan trắc tại hiện trường sản xuất, tiến hành nghiên cứu hoàn thiện biểu đồ tổ chức sản xuất cho lò chợ cơ giới hóa vỉa 11 khu Trung tâm - mỏ than Dương Huy. | 62 Journal of Mining and Earth Sciences Vol. 62 Issue 5a 2021 62 - 68 Improvement of production arrangement chart for mechanised longwall at Seam 11 of Centre area - Duong Huy coal mine Hiep Hoang Do 1 Tung Manh Bui 2 Dung Tien Thai Vu 2 Anh Tuan Tran 3 1 Company 35 - Dong Bac Corporation Vietnam 2 Faculty of Mining Hanoi University of Mining and Geology Vietnam 3 Vietnam National Coal - Mineral Industries Holding Corporation Limited Vietnam ARTICLE INFO ABSTRACT Articlehistory The mechanization of longwall mining is an inevitable trend in Received 28th Feb. 2021 underground coal industry. At present Vietnam has operated many Accepted 14th May 2021 mechanized longwall faces in Quang Ninh coal field. The mechanised Available online 01st Dec. 2021 longwall at Seam 11 Centre area Duong Huy coal mine has been operated Keywords and its mechanised equipment complex basically performs as designed. Duong Huy coal mine However the actual production shows that the longwall equipment has Mechanized longwall face not reached its maximum capacity while the arrangement of production remains inadequate. Apart from objective factors the initial production Production arrangement chart arrangement chart did not consider the maximization of the mechanised Working time. 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. Copyright 2021 Ha noi University of Mining and Geology.
