Gob-side entry retaining (GER) is a technique used in thick coal seam mining to keep a pathway for future mining. A new method was developed to improve entry stability and reduce accidents. By fracturing the roof and using special cables for support, the entry remained stable during testing. This innovative approach offers a cost-effective solution for mining in thick coal seams.
