Abstract: The "single roadway top coal mining method for steep and medium-thick seams" addresses the challenges posed by significant variations in seam dip angles and thicknesses. This approach segments the seam into multiple sections along its incline, with each section utilizing a single roadway aligned with the seam's trend. This roadway is dedicated to one coal mining section, managing the ventilation, transport, and pedestrian traffic for the working face. To ensure the effective execution of this method, numerical simulations are employed to examine the surrounding rock movement after the working face advances. Two roadway preservation techniques are proposed, tailored to different burial depths: the "flexible mold concrete wall" and the "flexible mold concrete wall + right-angle tram I-steel roof." Both methods undergo theoretical analysis and numerical validation. Practical application demonstrates that these techniques effectively stabilize the surrounding rock, prevent airflow between the roadway and the gob, mitigate gas accumulation, and reduce the risk of spontaneous combustion in the residual coal. This method enables efficient single roadway top coal mining and offers crucial technical support for similar roadway support challenges, holding significant theoretical and practical relevance.Abstract: The "single roadway top coal mining method for steep and medium-thick seams" addresses the challenges posed by significant variations in seam dip angles and thicknesses.
