Scope

High-mining face fully mechanized mining technology is an important method for the efficient mining of thick coal seams in China, with significant advantages such as high resource recovery rate and high production efficiency. Upward mining, as a special arrangement method of high-mining face fully mechanized mining, has important engineering significance in protecting the overlying coal seams, reducing rock layer disturbance, and optimizing the continuity of mining areas. However, the layout of upward mining roadways is affected by multiple factors such as the occurrence conditions of coal seams, rock layer structure, and mining-induced stress. Improper design can easily lead to safety issues such as roadway instability, support failure, and poor ventilation, which restrict the safe and efficient application of this technology.
