Công tác tổ chức sản xuất và bố trí nhân lực hoàn thành các công việc trong sơ đồ công nghệ khai thác hiện tại của mỏ gặp khó khăn, do đó để hoàn thành được một chu kỳ sản xuất trong lò chợ cần mất nhiều thời gian thực hiện, dẫn đến sản lượng và năng xuất lao động trực tiếp đạt được còn chưa cao. | 36 Journal of Mining and Earth Sciences Vol. 62 Issue 5a 2021 36 - 44 Improvement of mining technology for the longwall -170 -100 m in Seam H10 at East Wing of Mong Duong coal mine Tien Trung Vu 1 Ha Manh Tran 2 Son Anh Do 1 Dung Tien Le 1 Au Hai Thai 1 1 Faculty of Mining Hanoi University of Mining and Geology Vietnam 2 Mong Duong Coal Joint Stock Company - Vinacomin Vietnam ARTICLE INFO ABSTRACT Article history The coal production of the longwall -170 -100 m in the seam H10 at the Received 22nd Feb. 2021 East wing of Mong Duong coal mine has basically reached the designed Accepted 28th May 2021 capacity. Because the mining technology layout of this longwall was Available online 01th Dec. 2021 designed with only one raise in coal for travel and with one group of Keywords workers this layout cannot fulfil the requirement of increasing Longwall production of the mine. The production organization and labour Mining technology arrangement of the layout face difficulty cause considerable time for performing a production cycle and constrain productivity. Through a field Mong Duong coal mine study at the mine the authors propose a solution for improvement of Soft support ZRY mining technology layout of the longwall. That is another raise in coal Steeply inclined seam. and a second group of workers are added to the current layout. The associated production organization chart has been accordingly revised. The calculation results show that the production cycle time is decreased and the productivity is increased. The research results from the paper are important and necessary for Mong Duong coal mine as they form the basis for increase of coal production and labour productivity at the longwall - 170 -130 m.
