Taking the engineering background of the Baiyanzi Mine design in Gansu Province, and based on the occurrence characteristics of steeply inclined coal seams, the layout system of mine development roadways was innovated by following the principle of adapting measures to local conditions. By introducing mature domestic coal mining technologies and equipment, the underground mining system was optimized, reducing roadway engineering quantity and investment costs. This realized the intensive design of the production system, effectively lowering mine construction costs, significantly improving the level of mechanical mining, and enhancing the production capacity of working faces, thus providing technical guarantees for safe and efficient mine production.After commissioning, the mine exhibits the characteristics of a modern mine with "streamlined personnel configuration, outstanding production efficiency, advanced technical equipment, and remarkable economic benefits", integrating both economic and social benefits. As a pilot development project for steeply inclined coal seams in the Baiyanzi Mining area of Gansu Province, its construction has accumulated valuable engineering experience for the subsequent large-scale development of steeply inclined coal seams under similar geological conditions.
