An overview of mining design for a steeply inclined coal seam in Baiyanzi Mine
WANG Meng
Abstract：To address the technical challenges in steeply inclined coal seam mining,such as complex roadway layout,extensive underground excavation,and low production efficiency,an intensive mining scheme was designed for Baiyanzi Mine in Gansu Province.Based on the coal seam occurrence characteristics and adhering to the principle of site-specific adaptation,an intensive roadway layout system was innovatively proposed.By optimizing the industrial site location,development scheme,and selecting proven fully mechanized mining technology with matching equipment,an efficient and intensive mining system was constructed.The multi-scheme comparison and system integration method was employed to reduce underground excavation volume and construction investment.After commissioning,the mine exhibited modern operational features characterized by"streamlined personnel,outstanding production efficiency,advanced technical equipment,and significant economic benefits".This design provides a technically feasible and economically reasonable engineering model for the safe and efficient mining of steeply inclined coal seams,offering important reference for the large-scale development of similar coal seams.
