Abstract: In response to the problems of high ventilation resistance, high labor intensity of workers, inconsistency between mining speed and support speed, and high equipment cost in active advanced support using single columns and hydraulic supports for the ultra front section of the longwall fully mechanized mining face, taking the return air entry of the 5-20111 working face of Yulin Energy Qinglongsi Coal Mine as an example, on-site investigation and measurement, laboratory testing, and numerical simulation methods were used to compare and analyze the control effect of active advanced support surrounding rock under different parameters, evaluate the applicability and safety of active advanced support technology, and carry out industrial experiments on site.The results show that the surrounding rock of the 5-20111 return air entry belongs to a relatively solid rock with a stable internal structure.The surrounding rock is less affected by mining, providing good geological conditions for reinforcing anchor cables to replace hydraulic supports for advanced support.The advanced support scheme of adding one row of reinforced anchor cables to the roof of the roadway, with one cable per row, a spacing of 7.2 m, a tension force of 200 kN,and an anchor cable length of 6 500 mm, can effectively control the deformation of the surrounding rock in the advanced section of the roadway, improve the stress distribution of the surrounding rock, and meet production requirements.The active advanced support of reinforced anchor cables has been successfully achieved in the 5-20111 mining roadway of Qinglongsi Coal Mine.
