    In the early 1970s, demanding mining conditions in German coal mines set the stage for extensive R&D in roof support technology. Steeply inclined coal seams both thick and thin, weak roofs and massive sandstone roofs, soft floors, and geological faults called for a high degree of customization. The resulting expertise has been deployed and applied

    With the resources exhaustion of medium-thick and thick coal seam, the mining technology of thin coal seam has attracted more attention. Due to the little working space for mining in thin coal seam, blasting mining and high-grade conventional mining are main mining methods that were used in thin coal seam. Taking the 17th coal seam of Liyan mine as an example, in this paper we analyze the roof
